SVO, I drive a vehicle that has a fairly efficient engine, okay gearing if you don't mind 50-52 MPH but it's heavy (if only it weighed 1000 pounds less), and you realize just how heavy watching the ScanGauge whenever the road rises or falls and whenever you accelerate.
Just like cycling, what you lose on climbs you never gain as much back on descents, and the heavier you are, the worse the loss to gain ratio gets.
Not saying that I wouldn't mind way more gearing options as well. A 6 x 3 transmission in a vehicle could really help out as well. CVTs are an excellent concept but I have suspicions that they have a lot of friction and I am somewhat doubtful about their lifespans.
