Absolutely!!!
But why stop at Range Rovers? Almost all big MPVs weigh more than 2 tonnes fully-loaded. And let's not mention Jags, big Beamers, Mercs... 2 tonnes ain't a lot!
The real joke is when you get a panel van limited to 50MPH and you convert it to a camper van by putting a "garden shed" on the back, making it MUCH heavier AND more top-heavy, but somehow it's "safe" for 60! The manufacturers of vehicles that can be made in van or passenger carrying form are always completely bemused by the whole "car-derived / van-derived" thing. It is a completely meaningless concept in engineering terms. They are designed SIMULTANEOUSLY for both duties. More often than not, they have identical braking and suspension systems and (perhaps not surprisingly

) remarkably similar stopping and handling characteristics!
It really is one of the absolute gems of speed limit policy which, I think beyond all others, proves that the people who make them have very little understanding of what they are regulating!
