Maybe my perspective is coloured by the fact I use a HOTAS to control it, but I think that the SRV handles surprisingly well when it's barrelling along in low gravity across rough icy terrain at 67 mph. After hundreds of hours driving the thing, the only aspect of the SRV's handling I can't get over is the weird interaction between the wheels and the ground mentioned by
@DemiserofD on the previous page. It behaves totally backwards to how it has in every other game I've played with drivable off-road vehicles.
My general response to this so far has been,
1) It's better to fly if you can. If speed is of the essence, use the jump jets to hop between rough patches of ground and over small cliffs.
1) Don't go flat-out on the throttle, unless ground conditions are smooth enough to permit doing so without constantly spinning out. Keep an eye out for large rocks and similar obstacles and be prepared to activate the jump jets to avoid them.
2) If the SRV starts spinning out, hit the reverse gear to slow down and avoid becoming completely disoriented. Being in reverse gear in these situations kinda-sort of fixes the tendency for the SRV to move opposite to your intended steering.
