People buy a new car generally every 5-7 years.

furthermore there does not seem to be any great brand loyalty in the market

maybe because of being afraid of dying but probably not, but given how often people buy new cars (not that often) and the lack of loyalty, I think it would not make any sense from a business perspective to give a damn if the customers die (disregarding moral perspective which I'm sure is a primary concern for automotive manufacturers)
