Create mesh as driving lane behind vehicle


i am currently working on a project where i have a driving vehicle. Now i want to create a driving lane behind that vehicle with collision (like in tron). After a time it should begin to dissolve at its end.
My question now is what is best practise to implement this. I thought about a box brush which i scale while driving, but it wouldnt be possible to create nice curves with that. Then i thought about a paticle system, but can i have collision with that?
I hope you understand my problem.


Ok I search a bit around and found Unity has something like this called “trail renderer”. This would be pretty much what I am searching for. Is there something like this in ue4? All I currently found is only for particles. But can i have collision with that?
