Well, I’m blowed!
It could become advantageous, if not essential, to be able to adapt conventionally powered cars into hybrids. I suggest a simple method.
Devise a means to plug a hair dryer or leaf blower into your petrol or diesel-powered vehicle. Switch on the electric blower. Direct the flow of air in the opposite direction to that wanted to propel the vehicle. Drive as normal. You now have a hybrid vehicle.
