Okay Arrowhead, you gave us the FRV, you gave us roads. Now where's our map looping race track?

It's a simple idea that seems obvious. On low difficulty missions give us a few maps that have circuiting roads that run somewhat near the edges of each map. This road connects to itself to form a loop so that we can race our FRVs for as many laps as we choose. Barriers could run along the majority of the road to ensure the course is kept. Hell they could even make mission types out of it.

A "FRV Capability Demonstration" mission: Successfully drive 3 laps around the map in less than X length of time passing all checkpoints in their correct order.

A "FRV Emergency Civilian Transport" mission: Time is short. Use the FRV to quickly transport civilians to the extraction site before the shuttle leaves.

What do you guys think?
