I think drivers in cars or without trailers should have to use the motorway as they can just block up the C-D Route for truckers with urgent deliveries, and with the amount of people using the route at the moment, there are multiple crashes and plenty of blocking this can be quite annoying for drivers as you can enter the route with 0 damage and leave with 40+ on your trailer which makes the job pointless if you're just trying to gain cash and xp
