I have a few races that ive made a backstory up for and a reason behind them.
Ive made about 11 total so far would love people to test them out and give feedback.
Well I've just ran your first, delivering the meth or something I forget now and it's not bad but, I think it could do with some improvement. Firstly, I think if you're gonna give a mission a role, it can be carried by props for example, the stunt jump can add that little cut scene that can give the feel of a mission. Check out my own race 'The Chase' if you get 5 minutes to see the sort I think I did there.

For example, when you make the small jump into the 'down the drains' bit, a stunt jump added there would make it look and feel much more movie like. But props too, A trailer or simular added there could stop people doing what I did on both run throughs and that was, landing in the water which is frustrating and totalled my Feltzer on the 2nd run(good job we don't lose them in a race )
A gate with maybe some boxes behind would look good as you enter the lost's garage, again, give that movie feel and especially if you can make it go to a cut scene with a small ramp and a stunt jump etc.
Be careful with your checkpoints, I think it's the third one which is covered slight by a bush(or at least it is from my first person view) and the one that leads you into the train tunnel, you don't realise until late that it's pointing you down there and again, a prop or even a barrier added which forces that route for you could really improve the drivablity. Don't make me have to look at my minimap, I don't always see the oncoming car otherwise.
I completed the race/mission in 2:52.252 in my Feltzer on the first run but had a disaster in the 2nd. Hope this helps.
