They do, just not in their EVs.
I loved the Volt. To me a plugin hybrid is the only vehicle that makes sense unless you exclusively drive very short distances in a city and you can have in home car charging.
All of their new vehicles (except their EVs) have carplay. There is no stated plan to discontinue carplay from future ICE vehicles. They are doing it to their EVs because Tesla whipped electric car owners and now like 80% of EVs on the market do not support carplay.
And because of that decision I’m refusing to reward them as a company. It’s not specific to EVs vs ICE for me, or even new vs used. I’m tired of companies like GM going out of their way to harvest more data for their “trusted partners” so I’m out.
