> My model Y can effect a very reasonable stop in traffic without touching the brake pedal except to hold the car at the end. My manual car could do this 20 years ago. My fully ICE motorcycle can do it today. I know engine braking is cool but it’s not some amazing new thing only EVs can do. Altho granted it only produces heat and noise in petrol vehicles. But it also makes your heart sing so that’s nice
I have an ICE car and motorcycle, and an EV. The EV slows down much more quickly when slowing down, to the point where it's a good replacement for the brake, as opposed to the ICE vehicles, where you need to use the brake a lot more. It's not comparable.
Are you comparing to an automatic ICE or a manual?
In my experience of driving EVs their engine braking is sub-par to what I'm used to at least from my motorcycle. Bikes have silly high compression compared to their weight. You def have to be careful about chopping the throttle.

Do you have any idea how many hours the average person uses their phone? There is no other object that has been a greater detriment to mental and physical health in human history. This is just another instance where someone is willing to push something (only using public transport) on someone else because it fits their viewpoint, but you can't even consider something that would have a similar impact on yourself in re…

For DIY EV conversions (I built some cars) you usually hook up the "regenerate braking" to the brakelight switch. So as soon as you tap the brake pedal just a little, you start regenerating and see the amps flow back into the battery (I have a little display on my dashboard). Only when you press the pedal further, do you start engaging the friction brakes. I have no statistics on brake pad differences because we didn…
With a manual car, it was common to downshift and use the engine to decelerate. I’m wondering if electric vehicles might actually cause a return to a third pedal to re-add some of the fine tuned controls that a manual transmission allowed. Maybe the “downshift” could engage the regen brake specifically.
My EV is set on max regen mode though, and I sometimes drive without pressing the brakes, as there’s a paddle I can use to use regen for all my braking needs bar an emergency. It even has a name - single pedal driving.

I suppose the same should apply to hybrid cars, which outnumber pure EVs significantly [1]. The effect comes from converting the kinetic energy back to the battery charge via generation instead of wasting it via friction, which is the whole point of hybrids.

which is the whole point of hybrids Part of the point, not the whole point. Regenerative breaking is absolutely a win; but there can also be a significant benefit from allowing the ICE to remain in the RPM "sweet spot" rather than moving around a larger range.

I’m against a ban. That sort of pollution is an externality and we could price it in.
Based on the long history of trying to price in externalities, bans are probably more effective. Just look at how many games are played with carbon "credits", and how little real impact they've had.

The biggest problem for new EV drivers, in my view, is that EVs generally have extremely good traction control systems that prevent chirping due to the ability to cut back power to the motors much more quickly than you can with a gas engine. What this means is that you can push tires to the absolute limit and not chirp them (which, is best for traction anyways) which absolutely roasts them. Most people associate chir…
I went through my first set of tires in 10k miles. By doing car racing (on official tracks!) every month or so. Though it might fall under the "being idiot" category.
If you're track racing, it should be obvious you'll blow through a set of tires much faster than the treadwear ratings would suggest.

BMW tried that with the i3, it wasn't particularly popular. An engine, fuel system and a generator are all relatively complex additions compared to just putting the same cost and vehicle space into more batteries, and the public charging networks are definitely up to the task by now (having been EV-only for almost 5 years now).
I've ridden in one and this was basically a case of "you get the worst of both worlds". The engine was small and running at a constant RPM, leading to an annoying noise in the cabin. The range extension was not particularly huge. Worse, when we did eventually run out of battery on one trip, the range extender was unable to recharge the battery after refueling the car, forcing us to scramble to find an available charg…
Could you expand on this? What was the actual problem? For example, did the range extender start and run? Did it put any energy into the battery at all?

Range anxiety seems to go away after your first week of EV driving.
Eh, I'd say it goes away after your first road trip, unless you're going somewhere remote. I've had my BEV for about 5 1/2 years. My first road trip (Portland -> Santa Clara, ~560 miles each way), I planned it out ahead of time with ABRP. These days, I'll just let the nav figure it out.
I have been totally unconcerned about it since.
