I’d shoot for audio, and the radio is a safety feature, but I would make it a physical device in the center console instead of a giant touchscreen. Backup cams are mandatory in the US, I’d integrate that into the rear mirror to save space and sightline. I’d have the entry level model with a digital dash, and the option for an analog speedometer+discreet digital info displays. Power windows would be standard, but you could option for manual crank windows for a cost cut.

Some features of EVs feel like high tech bullshit until you actually drive them. Like heated seats and steering wheels. Heating the whole car is horribly inefficient, you get a lot more range if you can leave the heat off and just use the heated surfaces. I’d consider a heatpump too, but this involves some duplication of duty, since the battery pack needs a resistive heater to stay warm in the winter, and most EVs use that same heater for cabin heat.

I’d leave out fancy electronic doors. My MME has them, and the are really nifty, but the novelty does wear off. I’d ditch the power lift gate as well. Super useful, but I just know that shit is eventually going to break, and then it is going to be an expensive pain in the ass to fix.
