How many SUVs does it take to run an olympics?

GM has supplied over 4,000 vehicles for VANOC to use for the 2010 Winter Olympics.  They can be seen parked in several large lots in Vancouver and Whistler.  Almost all of the vehicles are SUVs.  Yes, a few are hybrids and there is one fuel cell vehicle, but most are just regular gas guzzling SUVs.

In the weeks leading up to the games the large white SUVs could often be spotted around town.  They almost without exception would contain just a single occupant.  A Squamish resident related seeing four stopped at a light all going the same direction and all with single occupant.

If VANOC was truly interested in sustainability couldn't they have found better transportation solutions? Why not public transit or even bikes for all those single occupancy trips?  Or at the very least they should have found something more fuel efficient than an SUV.
