This is not a tenable position. Most cars are older than these devices- and even big tech co's like Apple were late to patch flipper vulnerabilities. I was on a plane last month and someone was flipper-jamming DOS-ing via continual bluetooth connection requests and completely bricked all iOS devices in range for the 4 hour flight.

These sort of devices are nuisances with very low positive utility, and there is plenty of precedence for banning them.
