And you get paid for it, too.
That alone makes up for the removal of a Test Drive option in the tuning screen, imo.
Well yes and no, you get paid if you run a race. You do not get paid for test drive but once you have loaded the track you can test drive, tune, upgrade race, switch cars all without ever having to pick a track and wait for it to load.
It used to be you get a car, go to tune and test drive or just test drive. You then had to pick a track and wait for it to load. You drive it, maybe pause and tweak a little then you realize you need to add a upgraded trans to get the gear you need so you exit test drive, go to upgrades, install the trans then back to test drive select the track, wait for the track to load. Then you start driving and opps forgot to get brakes while you were there so exit .... wait for track to load. Now you only need to load the track and you can drive, tune, upgrade, drive tune, upgrade and if you want race.
It is way better than before if for no reason other than the time you can save when building a car. If only it didn't crash when you look at to many wheels.
Oh they also added the test drive, tune and upgrade options in the career lobbies so you can do the same thing there.
Did I mention that they finally added rewind to the test drive mode. This is a biggie to me, something I have been wanting since the first day they added rewind. Should be a real time saver tuning for the longer tracks.
