Again, a big difference is that EVs like Teslas are smart phones on wheels. They are wirelessly tethered to OEM HQ, collecting all sorts of data on you to send back to them. Tesla remotely monitors their cars and can allter anything about them over the air including range. A few years ago when a hurricane was going to hit a city, they gave Tesla drivers free temporary extended range upgrades, normally its an upcharge. So if you want to upgrade a Tesla you just pay Tesla to download tuning upgrades of to activie options already installed in the car. They can even remotely kill Tesla cars which means you can't truely own one.
People have hacked Teslas but they end up losing OEM support. They ard blackballed from services such as software updates and fast charging. My main problem with EVs is the insane monetization in them.
Mike kinda beat me to it. BUT
The ingenuity of the aftermarket will prevail.
It is kind of funny that the OEMs were generally protected by ignorance on the software side from the time of EFI's inception in the mid-80s. Sure chips and flash tuning happened, but it wasn't like the days of timing lights and screw drivers. The funny part is when tuning software suites came out in the late-90s where anyone could go nuts ruining factory tunes without consequence as the OEMs had no safe guards. Now in the current state of things the OEMs are using encryption and anti-tampering methods to prevent electronic circumvention. With the obvious next step being monitoring everything all the time OTA.
This is where the right to repair battle becomes the death of the muscle car. We, as hotrodders, want to tinker for speed and enjoyment. The OEMs cannot afford this model because it impacts their bottom line. So, to your point, it is a service-based or a la carte upgrade scheme where the OEMs offer unlockable warranty supported upgrades.
The problem is it takes it, the interaction of making the modification and the sense of accomplishment (and relationship building with said vehicle and brand), out of the hands of the enthusiasts. This emotive connection is what made the muscle car, the muscle car. Sure there are lots of chequebooker hotrodders out there but they aren't cut from the same cloth as the traditional hotrodder.
I don't care about your EV specs and stats.
You'll be the first one fabricobbling 3 motors per axle and stacking 75kwh packs through VFDs and arduinos.
