I'm thinking of designing a "car-po"
There would be 3 settings,
1. "Man". This would allow unresticted to all the vehicles functions as, quite clearly, men over 30yrs of age are the only people capable of handling such a machine.
2. "Juvenile". For use by boys (men under 30). This would restrict the vehicle's speed to something reasonably appropriate to the prevailing road conditions. It would also disconnect any audio equipment fitted to said vehicle.
3. "women". Would prevent the vehicle from starting. This would free up much needed road space during "school run" hours and have the dual effect of reducing carbon emissions and providing women with much needed excercise by forcing them to walk the 200 yards to the school gates.
No need to thank me, happy to help. ;-)
