Unfortunately you can’t force a company to use another companies technology (in this case android auto and CarPlay), only if that’s a genuine deal breaker for the majority will they adjust their strategy. If we’re talking about safety, better pay and conditions etc.. then you’re suggestions would absolutely help. The EU can do some things (such as the usb mandate for charging or all new cars required to have a SOS function to call police in the event of a crash) but these are open standards and not tied to a specific company.

While I agree with the sentiment, none of those things would have helped this situation, the only way they’ll learn is by not buying the product and causing them to lose money.
