The autmoatic gearbox has been available for cars since it was introduced as an option for the oldsmobile in the late nineteen thirties, but it has only really been over the last decade where the number of vehicles being made with an automatic transmission has increased dramatically. This is largely due to improvements in its technology, with computers being more advanced, and better able to determine the correct gear setting. It used to be the case that an automatic was far less fuel efficient, but this is no longer the case. The reason for the shift to automatic cars is readily apparent to anyone paying attention: they are far more convenient. Being able to drive along without worrying about changing gears is a luxury which more people are now willing to accept. We have seen further pushes to automate vehicles since automatic transmission was introduced, with the introduction of the automatic braking, all with the eventual goal of fully automatic vehicles.
