Car companies aren't finding making an electric car hard at all.

Taycan is by most reviews the best EV car out there. And we have EVs from BMW, Hyundai, Kia, Mercedes, Volvo, VW etc already being sold today in pretty sizeable numbers.

The problem is (a) getting enough battery supply, (b) convincing consumers to buy them, (c) getting the costs down and (d) the somewhat lacklustre growth in EV demand.
