I think the biggest problem with German EVs are not the battery but the software. EVs are practically computers on a wheel and compared to the competitors the software and features it offers are still terrible. I remember VW even had a huge joint venture with Rivian to get things back on track. But seems like it didn’t work out
There’s nothing about EV drivetrain that requires more complicated software than ICE powertrain. It’s just consumerism telling people that their next vehicle (whatever drivetrain) should be an iPad, a home cinema, and a PlayStation all-in-one.
