"In this context, there’s another number there that I think is really interesting: The “km/c-h”, how far you can get on an hour’s charge. For this particular car on this selection of chargers, it was over 200km (124 miles) per charge-hour. I think that’s enough? Maybe in the lower regions of enough, but there." So at 110km/h, less than 2 hours of driving for every hour spent charging? In what world is that close to "…

Yes it is ridiculous to claim that this is somehow minor. That said, there are electric cars far better for road trips than the Jaguar mentioned in this story. A long range Tesla Model 3 will easily do about 350km within its 10-80% state of charge bounds and the charging stops can be limited to 20-30 minutes each. Experienced EV drivers with good EVs can achieve 100km/h average speed INCLUDING stoppages for charging.

You seem to be right that the Jaguar is a poor car for road trips. A Hyundai Ioniq 5 will charge in half the time as a Jaguar I-Pace, and the car costs about a third less.

It cost me a simple written exam (free) and a driving test (free) and then about $25USD for the actual license when I was 16. How much does it cost in the UK? If the barrier to drive is low, you end up with people driving around that got a 70% on the written test (lowest passing score) and a 70% on the driving test driving around doing stupid things. It drives up insurance considerably.

Uhm, in the UK you can only pay for the test if you want, no actual training is strictly required. So....like £99 or there about? But of course majority of people pay for training because they want to learn somewhere, and not everyone has parents willing to risk the family car. Surely even in US people pay for training and there's more to the cost than just the $25 test fee?

Most families in the states have more than one car, so there’s less risk to teaching your kids how to drive. There are schools though, but I never had that (neither did my wife, apparently). My dad was an insane teacher though. He’d have me slam the brakes in the middle of an empty highway to learn how to stop at-speed. I’ve never been in an accident (knock on wood) but I’ve seen more than my fair share of deadly accidents happen right in front of me.

Is anyone working on an active adapter to make a Supercharger think the device on the other end is a Tesla vehicle, so it'll put out a charge? I have no idea how Superchargers work, but I assume there's some sort of active electronic handshake going on over some control pins to authorize power delivery — perhaps even something cryptographic, e.g. the "pump" and the car both having Tesla-signed TLS certificates and pe…

Tesla are supposedly opening up their network soon, but that's not really the issue. Cars have a limit on how fast they can charge, and for a lot of more economic cars that's often quite slow. The 2022 Nissan LEAF 40kW (149 mile) model can only charge at 50kW, the 60kW (226 mile) model pushes that to 100kW. The marketing says that's 45 minutes to 80% capacity. The 2022 Chevy Bolt is similar. If you are just commuting…

Sure, but a car isn’t the only thing you could potentially plug into a Supercharger. (That’s why I said “the device on the other end” rather than “the vehicle on the other end.”)

Maybe you just want to charge the gigantic custom-built battery bank you use for accessories power in your RV! Or maybe one that’s just a hacked Tesla Powerwall or five. (That’d be the “white-hat” use-case.)

Or perhaps a portable (towable) hydrogen generator, to fill bottles for hydrogen-powered cars. Still an “adapter”, technically, though doing it at the substation-level rather than the near-power-generation HVDC level is probably horribly inefficient and wasteful.

Or perhaps a mobile Bitcoin mining rig consisting of server racks installed in a air-conditioned shipping container on the back of a semi-truck…

Or the lighting and sound for a pop-up roadside rave event!

Again the feds encroaching on state powers.

in canada, all governmental power belongs to the federal government. provinces only have authority when it is granted to them by the federal government. there is no such thing as the feds encroaching on "state powers" because provinces are not states.

It's not true that all government power belongs to the federal government and that provinces only gain power by devolution from the federal government. The Canadian constitution describes areas of responsibility for both the federal and provincial governments with some shared areas of responsibility.

I just did a 2 day 2000 mile trip in my long range model 3. Total charging costs were around $100, which didn’t include two stops where the superchargers were free (network connectivity problems?). Required a total of 13 supercharging stops. Each stop was between 20min to 45min. I started off completely full, and charged overnight at a Tesla destination charger, (so, 14 stops?). Roughly half the cost of the article’s…

The non-Tesla public chargers I used are pretty well all at gas stations or big-box stores. So there's always a bathroom, a fast-food joint, and sometimes even a real-food diner.

This is the insight that I need. I'm all about EVs, but my fam and I will go on at least 1 500 road trip each year, and we don't stop for sleep (unless we have to).

Assuming you're saying "one 500-mile road trip" per year, I don't think you should let that stop you. That's one or two 10-80% charging stops max for any Tesla. I'd play with https://abetterrouteplanner.com and test your potential road trips with the type of car you're interested in. It'll plan out where you'd need to stop, for how long, etc. Pretty cool way to alleviate (or confirm) your fears.

ABetterRoutePlanner is cool but in my experience extremely optimistic and doesn't include fallbacks for blocked/broken chargers.

Are new ICE cars affordable? EV don't cost 4x more than ICEs, do they?

Can easily be, if you compare comparable. I buy BMWs for cca 25% of the price of new (that means 6-7 years old and up to 100k km). Last one lasted 11 years and still counting. Maintenance costs are almost 0, apart from mandatory stuff (oil, brakes & pads, wheels every +-5 years). Hell will freeze sooner than we will be buying a new car - its just such a stupid waste of money, when the price drops so rapidly and you s…

Well, if you compare used cars of course ICEs are much cheaper, because the market is so much larger. That+s why I asked for new. It seemed surprising to me that you'd even consider a new car when an EV is that expensive compared to income.

Regenerative braking means that your regular brakes are used much less.

No less than with a manual transmission car. I went 5 years before replacing the pads on my last car, with 150k km driven—not because they were worn, but because they were falling apart.

I haven't driven an EV yet, but from what I hear regenerative breaking is much stronger than engine breaking with a manual car and can essentially bring the car to a stop in city traffic.

I took a look at the site as well, and planned the DFW->LA trip I mentioned earlier in the thread. I was shocked at the number of stops required just to get to the Texas border. That's normally a full day, but now it is 2 days. It's just not viable yet for cross country. I'm not saying stop EVs. I'm just saying stop with moronic concepts of using something it's not designed for. A 300 mile range is plenty for 99% use cases. Solve for the low hanging fruit. Lower pollution in cities where it collects the most. Then, continue working on larger battery capacities for longer trips. Harping on the viability is of what we have now is good is just doing a disservice.

From the end of TFA: >And everyone should stop driving fossil vehicles starting now. [ ... ] There’s no excuse not to. Admirable sentiments, but can anyone point definitively to the net gain/loss in CO2 terms of actually ditching a fossil fuel based car and replacing it with a new EV? And how does that look if the FF car is something like a Honda Fit (good mileage, lower than typical emissions)? I'd be willing to dum…

It would probably not be a great idea to destroy a perfectly fine ICE, though even that can in some cases be a win, if you drive very high mileage. But that isn't the point. We should stop buying new ICE vehicles as soon as possible. So instead of buying a new ICE vehicle, which might be on the roads for another 10-15 years, rather drive your existing one a bit longer and then switch to an electric vehicle. Currently…

> But that isn't the point. We should stop buying new ICE vehicles as soon as possible.

Well, I agree entirely with that. But TFA said we should all stop driving them now, and that's what I was asking about.
