Just to collect some GC I am running Project Impulse with my fully upgraded Renault Dezir.
On day 4 ( goal 1 ) I had to do an enduro at the Indy Oval and instead of stopping directly after becoming first I just went on. This was not a bad decision because already quite soon there was a train. Unfortunately I crashed around the 30km mark. But I got the idea more was possible so I triceps it again. And yes if you go on you will get a lot of trains. This timeI crashed into 2 cars around  95 km, but more is possible if you are able to avoid big crashes. Even when my topspeed dropped from 294 to 290 km I was still able to catch trains and pass cars.

My final score ( with agent for fame ) was this:

Edit: It is day 3, not day 4 !
