Heated seats are a must if you drive anywhere that gets cold. Saves you a lot of miles. Backup cams are mandated on cars in the US now, and if you’re gonna have a screen, you should probably include some navigation so the car can pre-condition the battery before you get to a charger.

Well, if you’re gonna do those (pretty necessary IMHO) QoL concessions, you might as well give the user the option to integrate it with their phone, so they don’t have to wonder if the car got enough charge, or if some asshole yanked out the plug. If you’re reporting that info to the phone, you can include some controls to start/stop charging or set certian charging targets for certain charging stations. If you’re including controls, you might as well piggyback some basic lock, unlock, pop trunk features to the phone, and if you’re already letting the phone unlock the car, you can pretty easily include proximity unlocking. Since you’ve got a data connection to the phone, you can stream music and data from the car to the phone and vis-versa. You could put in another screen and physical controls for managing the music, but you already have one in the car for the rear cameras anyway, so why not just integrate the whole damn thing and now we’re at most modern features of EVs, minus the goofy handles and driver automation.
