I've been looking at lots of ramp safety/proper use articles but they all seem focus on lifting the front of the vehicle.
On a vehicle with enough clearance to use a ramp at the rear tires, is there any reason you should not lift one whole side of a vehicle by placing ramps at the front and rear tires and driving up? Assume the tires on the other side would be blocked, parking break on, etc.
You can lift one side safely as long as the center of gravity doesn't go past its tipping point, which will usually be the wheels on the non-lifted side. How far you can lift it depends on the vehicle, SUVs, smart cars and the like have a higher center of gravity than a sedan or sports car, so could be lifted less. You would need to find out the tip angle of the specific vehicle and do some calculations based on that.
