The future seems to hold both a worsening obesity epidemic and ubiquitous electric cars.

Today’s invention seeks to use an aspect of car design to help solve the problem of flab.


This is in the form of a car which, when parked for a set time (eg 30 min) after having made only a short journey from home (say 1km) refuses to restart for an hour or so.

This would encourage everyone who uses a vehicle for very short journeys to walk there instead (or to walk the short distance home).

It seems that the health benefits of only a very small decrease in car use are significant.

Over time, the 1km might automatically increase in order to reduce car use and improve exercise still further. At some distance, a bike rack might unlock, enabling even longer return journeys.
