Personally, the existence of a car infotainment system is a disincentive for me to buy the car. I certainly won't use it, and would prefer not to pay for it.
If that system is required in order to control a car's functionality (windshield wipers, etc.), then its existence is not just a disincentive, but a dealbreaker.
Imagine if car manufacturers started offering cars with no infotainment OS, and as users having a choice of open source OS distros to install on them..
