The highway is actually not difficult because the road obstacles don't change, but what makes the highway very difficult because the distance to get fuel is very far, so on the highway you have to need a vehicle that is super fast and fuel resistant because the fuel distance is very long.
I’m surprised by the diversity of the cars used in these world records, you got g.race car with two big wheels and you got g.race car with one big wheel 😂
I was so proud of myself completing 15000m in highway. I never could have imagine people going beyond 400k. Btw using moon rover on forest and mountain was nice and tactical move. None of the other cars can work there after a certain point.
