By design, all nodes on a CAN network receive all frames, which is the root of the problem. There are some differences in ECU validation, plus whether or not the vehicle supports UDS diagnostics, but these are differences by manufacturer and have nothing to do with the continent the car is being used on.
however, it's clear you're right - Zoom doesn't prioritize the product.
Also, realistically, wi-fi isn't the boogeyman here, even though the person you're replying to has been doom-posting about it for years - UWB and various other tech is going to make detecting location and movement from RF frequency fairly trivial.
Instead of just cancelling the ride, he reported me for being maskless in order to get a free cancellation that didn't hurt his driver profile. When I wrote Uber Support to explain I was wearing a mask (and had completed a mask-photo before I could request my next ride), they lectured me on mask-wearing and essentially accused me of lying. Note that I have a 4.9 star rating over 5,000+ Uber rides, so it's not like I'm an infrequent customer or repeat trouble maker.
