Only if you bought a car with all the toys. but most new cars have an alternative system. The radio. they broadcast traffic data to your radio and they could theoretically shut your car down with the radio. Mine has a traffic map that gets it data from FM Radio stations without the radio even being on. I look for them to utilize that for people that don't have an onStar system in their vehicle. I don't pair my phone with my car because....
That system is so old it's amazing it's even still on the air. It's essentially RDS but with other information onboard.
Maybe they are keeping it alive for a reason. it was upgraded in 2015 to 2kbps from 1kbps, graphic capabilities were added and sms support if radio supports sms. It would be pretty easy to embed a computer control feature to shut an engine off if they chose to. they wouldn't need to rely on the onStar system. I can see a nefarious application if they choose to.
Chances are most of these cars have an XM downlink already, this is the more logical choice as satellite radio data can reach places there aren't any FM signals floating around.
saw this and couldn't help but to think about our recent conversation: https://www.kuow.org/stories/we-didn-t-mean-to-ruin-your-mazda-s-stereo
Stopped reading when I got here:
A few weeks ago cellphone companies switched to a 5G signal. But many cars are still only equipped with 3G and glitch when faced with the newer 5G.
That's not how cellular or radio works.
