Well engineered ICE cars are the opposite of unresponsive. Gear shifts are in the order of 100ms. Turbocharged engines require some revs to get moving, but good engines rev so fast that unless you have no idea what you're doing this isn't a big problem.

Electric cars are like synthetic computer benchmarks - amazing on paper, but to actually drive? On a real road, with corners and a competent driver? So, so much worse. We'll get there, in time - some hybrids are really great, but we need to work a lot on battery weight before a pure electric car can match an ICE/hybrid car for real world performance. Weight always has been and always will be the enemy, and right now a tesla is closer to a truck than a sports car in terms of weight. The day will hopefully come, but today is not that day.

100ms of gear shifts is 100ms more than an eletric car without multiple gears.

Engines need time to rev fast, that's the problem yes. I don't know what you mean by good engineered ICE engine because I don't drive the worst at all and it's not good. Do you mean the super sporty 600kW ICE engines you find in supercars that cost a fortune to maintain and pollutes a lot?

Hybrids are shit in my humble opinion. You have the worst of both worlds, and not the best.

Weight is a problem but weight distribution is important too. And yes Tesla cars are heavy, as is tradition with American cars : a lot of torque and power, heavy, shitty brakes.

But I think that any car today is much faster than what you need. The roads are not a race.
