The weight of the amount of batteries required for a halfway decent autonomy ─ say about 400 kilometers, or some 250 miles, and that's still quite below the autonomy of a petrol-/gasoline- or diesel-powered car ─ is already enough to turn a sleek sports car into something with the inertia of a loaded van. And weight is very bad for the handling. It's extremely hard on the tires when cornering and braking, but that inertia will become even more dangerous on a slippery underground of ice and snow, when the tires have virtually no grip anymore. This poses significant challenges for the engineers of tires and suspension systems. Down force by way of aerodynamics is Good™, but weight is Extremely Bad™.
Another thing I don't like is the trend toward completely autonomously driving vehicles for personal transportation. What's the fun of stepping into your own car and being driven somewhere by a robot? Plus that the people who buy those things will soon no longer know how to drive a vehicle themselves, and thus, how to manually intervene when things go bad.
I mean, look at the USA... More than half of the US population doesn't even know how to operate a vehicle with a manual transmission. Not that there's anything wrong with a good automatic ─ emphasis on "good", i.e. with at least six forward ratios and a torque converter that locks in all forward gears ─ but it's not like manual transmissions are a thing of the Stone Ages. They have always been around, and most manufacturers in Europe and the Far East still regard a manual transmission as the de facto standard ─ many people even find a manual "stick shift" more involving than an automatic or a twin-clutch transmission. But in the USA, the vast majority of regular automobiles for the private market have always been torque-converter automatics since the 1950s, and the standard US driver's license doesn't even cover being able (or legally allowed) to drive a vehicle with a manual gearbox.
If you're going to cater to laziness and/or stupidity, then lazy and stupid people are what you'll attract ─ that's a proven fact.
