I finally found the finish! But I didn't know how to exit, as Escape puts the menu behind the results so Alt+F4 I guess :-D
Some other comments:
1. At the start it says CHAMPIONSIP not SHIP
2. There are 2 Union Jack flags
3. The concrete area was confusing to know where to go as the entrance and exits tend to blend in
4. Sometimes I flip and there's no key to get the car back on it's wheels (unless I missed something)
5. Sometimes the game launches with the car going flat out (after a restart occasionally)
6. It'd be MUCH easier if there was a spoken co-driver, rather than having to look at, and decipher, coded letters
7. On Xbox (360 at least) controller, the same X button activates hand brake and the headlights
8. Might be nice to have a cockpit/in-car view too.
9. And/or some way to turn down the sun! And possibly remove some of the VHS effects. But I see the graphics settings are all interim at the mo.
Overall, good stuff, lots of promise I think.
