Can't really defend the Ambulance, just a waste of development time which will be used once and never be seen.again, if you already had a 1000 cars in the game then ok, it's nether iconic mor useful in a closed circuit racing game.
It's just seems to me that's theirs no plan from PD, cars are just randomly done, Alot of complaints could be silenced, with a simple formula regarding cars, If you're going to release 3 cars a month, a simple formula of one Road car, an iconic car (which could be either race or road) and a race car, would IMHO silence most of the moaning, including from me.
Considering the online portion of the game is built around GT3 there's been as many vans as new GT3, cars, in the last year. Just seems bonkers to me,
I agree with your first couple of paragraph but don't have the confidence of them delivering on your final thoughts. I hope your predictions come true
