Car Buying Process Needs to Change

I understand this is a first world rant, and I am very fortunate to be able to contemplate buying a new car, but the process needs to change! Why can't we just be more up front with pricing? I understand online car buying exists now, but I'm a relatively tall person and I really need to make sure I fit in a car before I buy it. Anyways, rant over! Hope everyone is having a good week.
