Side stepping the fact there are tons of reports showing one the biggest miner of consumer data is coming from the automotive industry, I honestly would prolly leave these on for any self driving automobile i buy for the purpose of improving the perfomance. Im in a weird niche of IT community who doesnt just opt out of every data requ3st i get. If its a new product/service or isnt owned by google, ill generally allow the data request to help their development team.
