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.

I think I misunderstood your use of "actual pedal" in the GP comment. You meant accelerator by that? I assumed brake pedal

My point was that unless you do something bizarre or go out of your way to make regeneration not happen (e.g., hit both pedals at once, or shift into neutral while braking), the friction brakes will never get used except for when full regen is already getting used.

My 2018 Ford escape has auto-stop/start when stopped. But it almost never works. No idea why. It worked for the first year maybe, then disappeared.

It can be turned off, and there's very little visual indication that this has happened. The feature bugs some drivers, so if you have a second driver, they could have easily done it.

I've toggled it many times to no avail.

I don't think most people see car commuting as a luxury. It's very stressful.

Tough to say “most”. You’re probably right but a non-zero amount of people who pay luxury cars like Mercedes/BMW want a) status symbols but b) the time they spend in their vehicles as enjoyable.

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…

> That electric car is still creating a lot of particulate pollution from the tires on the road I hear this a lot, but how much pollution is it really? It surely doesn't register on any municipal particulate measurement station.

I had a link once to a government paid for study that claimed tire and brake dust were about 5-10% of the dust produced by light cars. The rest being tailpipe emissions. Of course brake dust, tire dust, and exhaust PM2.5 aren't the same types of dust. So feels to me like grasping for straws especially considering no one makes the same arguments against large SUV's and trucks.

> 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.

Society has made the choice so far to make owning a car as convenient and inexpensive as possible, while allocating almost no resources to other options. And no, usage fees including gas taxes don't cover the cost of roads -- let alone the land usage, externalities, and supporting infrastructure like drainage.

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…

I love driving as much as the next person but being on the roads at commuting time is hell on earth. Battling all of the other sleep deprived idiots to travel 3 miles in an hour. It's awful.

The people doing 151km trips aren't doing that. They're only spending the "busy" end of their trips under those conditions.

And their increased weight makes them much harsher on roads than normal cars. They wear down roads faster, and I suppose they also produces more particle pollution than normal car for this reason.

Any light vehicle traffic is basically inconsequential for any road build to handle any amount of medium trucks or heavy trucks.

Complaining about the 9000lb EV hummer makes for some great circle jerks among the demographics that hate people who drive normal hummers but the road basically doesn't care about them.

Yeah, that's my point. A single garbage truck is going to do more wear on the roads than thousands of passenger vehicles. Anything besides industrial vehicles is negligible.

A garbage truck has many tires to distribute the load. Also they accelerate/decelerate differently.

The rear tandems of a semi or heavier straight truck (garbage truck, dump truck, etc) occupy roughly the same road area as your car and may be carrying the weight of ~10x your car. The contact pressure is also much higher (100+psi tires vs your 20-40 or so).

And not to mention the epidemiological aspect, hello covid. A compromise situation could be individual transport but much smaller than current cars. Because EV's scale much more easily than ICE technology it's practical to have EV's with, say, a three person occupancy that take up half of a current car lane. This is the best of both worlds. Single occupancy vehicles and a city's transportation infrastructure doubles…

E-bikes are quite close to what you are describing, and are already remarkably popular.

Speaking of range, ebikes today vary a lot, some do 100 miles but some can only do 20 (which wouldn’t even get me to the office on the shortest route).

Model Y in cold climate here. While the sticker estimates of range are probably advertising, and the % battery to range meter you get in the app / dashboard is junk, the drive estimates are spot on . When you enter a destination, it will tell you very precisely how much energy it will take, accounting for every current condition, including temp. This must surely be data driven because it is alarmingly good. So your d…

This is the point my EV-skeptical relatives don't get.

"What are you going to do if the battery runs out in the middle of nowhere?" they ask.

"The same thing you will do if you run out of gas in the middle of nowhere: Call a tow truck." I reply.

I cannot get them to understand that they're asking the wrong question. The right question is "How do you ensure that you won't unexpectedly run out of energy?"

They don't run out of gas in the middle of nowhere because gas stations are everywhere. I don't run out of energy because the car does an exquisite job of tracking and predicting energy usage, as well as helping me find charging locations. It's an alternative (and IMO better) solution to the problem of running out of energy, but too many ICE drivers cannot conceive that there even could be another solution than "gas stations everywhere."
