Steering Wheel? Manual cars would be a problem
Most rentals are manual, and only intermediate size has automatic.
The problem is, some roads are so narrow, that were not meant for trucks when they were built now have many truck traffic - when you have an oncoming truck, esp making a turn, and you are in an intermediate, with the other side being obstacle (mountain, stone fence, whatever you name it), you would hope you are in a sub-compact!
