In freeplay DRAG, you can no longer control your revs at the start of the countdown. It reverted back to the original way, which makes it beyond annoying to tune again in freeplay. It was perfect. Please change it back…
I have noticed also that all my tuned RWD cars now doing wheelies on launch. I have to retune all the cars again 
It seems that Test Track has a lot more grip now, I don’t really know if this bug has anything to do with the new collision system.
me as well …please fix…thx
