unfortnately i'm one of those unlucky owners with a hill driveway that swings left into the garage. And I have to use any momentum from the road to climb that hill so that I can enter the garage without gassing and without stalling. As well backing in with a manual uphill stinks since you have to burn a lot of clutch to prevent sliding down again. I understand when your on a hill, the car rolls back a bit, is this too with the prius?

i got around 20 km a liter when i drove a civic 5 spd using advanced hypermiler techniques
and now I drive a salvage nwh20 prius that gets almost to 25 km/l with 195,000 km to date.
