To think that a gateway configuration can lead to liability issues or brick some system down the road is to not understand what we're asking for.Actually, liability likely is why Tesla has to (or already has) clamp down on this harder and make it abundantly clear they don't support this if they don't intend to do so. So if they do any software updates and something screws up because it's a part that doesn't match factory configuration, it's all on you when they have made that clear. It's a different case if they decide to officially offer retrofits, but obviously they have no plans to do so at this point.
Tesla has a documented procedure for configuration change post delivery, we know they do it, have done it extensively during the chips shortage on much more complicated and critical systems without issues.
To the liability crying posters, do you think if Tesla ran out of reflector headlamps, they wouldn't install matrix under warranty? Or if they ran out of matrix can you sue for installing reflector?
We are not asking tesla to install aftermarket parts here nor are we asking them to do something they haven't done or for free.
