IMO it is not very realistic that the vehicles can drive offroad as fast as they can on the roads. You always see the jeeps and trucks racing through the desert as if it was an autobahn. In RL the offroad terrain is usually very bumpy and you have to slow down a lot if you don't want to damage your suspension. Wheeled vehicles also have a reduced traction on off-road terrain.

Therefore my suggestion is to drastically reduce the speed of vehicles when they leave the roads.
- Wheeled vehicles lose 50-75% of speed
- Tracked vehicles lose 25% of speed

I know that you can have different ground materials in BF2. Is it possible to assign different vehicle speeds to them?

The reduction of off-road speed would also put more tactical importance to roads and half-tracks.

What do you think?

I hope this was not already discussed in the olf forum.
