Interesting that driving style has such an outsized impact. Perhaps aggressive driving and tire composition should be regulated.

There is no way to regulate aggressive driving other than to take people off of the roads.

For occasional commutes, 115km one way is ok (not for me, but it's not unthinkable). But 115km each way (230km round trip) 5 days per week is a problem. We should not be doing this, at least not in individual cars. That electric car is still creating a lot of particulate pollution from the tires on the road, not to mention its contribution to general traffic. The focus should be on how to reduce the commute distance…

I think this is the wrong way to think about it.

It's not about taking away people's cars, it's about making public transit so good (and building cities/neighborhoods that you don't need a car in), that you don't want to take a car, because it's less convenient.

I think this quote really nails it: "A developed country is not where the poor have cars, it's where the rich use public transit"

It's also worth noting that car driving is the worst kind of positive feedback loop (not a positive thing). Cars need Parking, which makes it harder to put things close together, which makes you need to drive places to get there, which makes you need parking. And cars are much bigger than humans, so the amount of space needed for cars, also increases much bigger than it would for humans.

Personally, my time in my car is some of the only pure "me" time I have, and I would hazard a guess that it is the same for many others. A car to me is a personal, climate controlled cocoon, where I can turn on whatever music I want, have a coffee or a snack, and escape for the 30 minutes or however long it takes to reach my destination...without the chance of being bothered by anyone else, much less any of the other…

Okay, but what if we could do that in a way that each person didn't take up 100 Sqft?

I get it might not be exactly the same, but walking/biking/Public Transiting with headphones in for a period of time is all that and more. And with the exception of a bike, you can do all of those things without having to sit in traffic...

> you brake with the electric motors first This is not true. At least for Teslas, the brake pedal only controls the friction brakes (they are hydraulically coupled). Same with a Chevy bolt. Unsure on other EVs

In Teslas, any time your foot is completely off the accelerator, you're getting maximum regenerative braking. If you then press the brake pedal too, you're getting maximum regenerative braking plus friction braking.

Teslas don’t use regen on the brake pedal. That is only using the friction brakes.

Right, but they use regen just by releasing the accelerator. So unless you're hitting both pedals at once, you will be regenerating every time you're braking.

While EVs do use less brakes than ICE, they still should last a lot longer than you give them credit for. Of course it's depends on how you drive, but if you are not getting 100k miles out of your brakes the problem is not the car but the driver.

> if you are not getting 100k miles out of your brakes the problem is not the car but the driver. This is just false. If you get 100k in your non-EV before having to replace at least your front brake pads, you must be racking up highway miles.

You are very out of date, on a modern car the rear brakes will go first. With traction control they move all the braking to the back, if possible, so steering works better. Of course if you brake hard there is no choice but let the front brakes take over, see my comment about bad driving.

Yes, Tesla is an outlier in the EV business. They only have one-pedal driving with regen or fully friction braking with the brake pedal. That is not true of the Chevy Bolt. Almost every other EV (and hybrid) on the market does blended regen with the brake pedal. Regen is applied when you first press on the brake pedal. As long as the pressure is mild to moderate, regen is used. If you press hard (as in emergency brak…

Well regenerative braking is limited and even more limited when cool. So Tesla's trying to train you to use the brake pedal when you want stronger braking. Makes sense to me, last thing I want is to get half as much braking as I expected.

So with regen I get variable braking, but I get a reward (more range and less brake wear) if I plan ahead enough to make it work. However if there is surprise or immediate need for more braking then the brake pedal is there. So it's pretty much the best of both worlds, once you get used to it.

If you use both pedals at once it will reduce acceleration and warn you.

Why do Americans care so much about resale instead of just using the stuff you bought? If I ever buy a house it'll be to actually live life in it, not to nickel-and-dime some poor college student.

Because the better the resale, the nicer the car you can afford to replace it. Most new cars are kept for 3 years and traded in, (or leased) so the better the resale the more money to put into your next car. Or if you lease the less your lease will be. Those who buy used cars keep their cars longer, and are willing to pay more for a car they think will last longer.

Why not just get a much nicer and reliable car and keep it for 10-15 years?

> Societies don't need to ask citizens to choose a given mean of transport; they can route their choices them by making some means more convenient and other ones less. I'm reading that as, "we don't need to ask , we can just make them do it." Which to me is pretty arrogant.

The US already "makes" commercial and residential building developers dedicate large proportions of their lots to meet minimum parking requirements in order to make it easier for people who want to drive do so. Is this "pretty arrogant" as well?
