Optimised acceleration/deceleration would probably save more fuel than self driving hardware uses, for city driving at least. At 60mph you'll be using 10-20hp

Optimised acceleration/deceleration would probably save more fuel than self driving hardware uses, for city driving at least. At 60mph you'll be using 10-20hp to maintain speed so about a 1-2% loss per 150W chip(well a bit more for conversion losses).
