Also, a bigger motor can be more reliable, if you're not running it at full bore you've probably got better heat dissipation so it will last longer.
The other issue is people's addiction for large vehicles; bigger vehicle means bigger battery means more weight means more power needed to move everything. As an example a Blazer EV weighs 25-35% more than the ICE version. Take that with the comments about reliability, it counter-intuitively makes a lot of sense that the Blazer EV has a 500hp motor vs the 200-300HP in the ICE.
As far as 'acceleration' itself, Acceleration tends to be more of a factor of torque curve. Electric motors tend to give lots of torque very quick... I accidentally chirp the tires on my Ford Maverick in a year more times than I was ever able to do even trying in my WRX. [0]
[0] - Sure, the WRX is all wheel drive but it's also a good 450 pounds lighter than the Mav.
The i3 is rear wheel drive but it's also rear wheel motor. Bigger skateboard battery means lower center of gravity. But perhaps the biggest factor is RWD the drive wheels don't have to steer (I'd say at least 2/3 of my 'chirps' were starting a turn). I'd be willing to wager the BMW has a better TCS software too.
Also I don't run stock tires on my Maverick, I run DriveGuard Plus[1] which are probably less grippy than the standard tires.
[1] - FWIW The WRX has 'OG' DriveGuard tires, The Plus supposedly are a -little- more grippy... Only lost 1 or 2 MPG on the Maverick changing to them from stock.
All you're doing is letting a dickhead bully win and letting bad people get away with bad behavior.
If I'm in my WRX and I do need to go above 75 quickly, I can drop into 4th and get to 80 more quickly. But I've got a stick so I can do that. If I'm in something with a slushbox, I have to wait for the thing to decide that downshifting is needed before it will pick up. I'll admit the Toyota Hybrids hit a good 'in-between' for these (probably closer to an EV than either a Manual or a slushbox.) I'll get a bit of instant acceleration but anything after a half second to second is a bit slower.
If he's riding your rear bumper for 5 miles after the fact, well obviously he wasn't in that much of a rush to begin with.
This morning I was in the rightmost lane doing 5 over and I indeed had someone come up at me 15+ over and ride my ass.
Was I supposed to just pull over to the shoulder at that point or kowtow?
Sometimes, but not so common not in my experience.
But I don't think a powerful engine is needed in that scenario either. The only case where it's really needed is accelerating up a steep hill.
