Actually the bad part is not even public roads driving. Straight line acceleration on a good road is fine.
To me the real danger is on parking lots and in slow maneuvers.
Where even a powerful V8 will need a few fractions of a second to wake up, pull up and pick up if you smash the accelerator by mistake, most EVs will be able to get you to stratospheric speeds without warning within a few car lengths.
A teen or an elderly person smashing the accelerator by mistake on an EV can do a number real quick.
Also, we're getting at levels which are beyond fun. I've been in an S Plaid doing pulls on the road, and I am absolutely convinced that we are reaching levels there which can be harmful to people with health problems. The acceleration is painful. I never though I'd say it with a straight face, but - by moments it's too much.
So maybe it could be a decent idea not to prohibit this, but maybe to regulate it so you can't get in rocket mode without going through a menu or a button or something.
