Abstract
Abstract A safety automobile is reduced in width compared to conventional vehicles and tapers forwardly to nearly a point to minimize head-on collision danger and provide lateral deflection of the vehicle to left or right on striking an obstruction. A dual power system is provided for maximum economy. A rear wheel electric drive is used for short range in-town operation and a front wheel internal combustion engine drive is employed for long range travel. The two drives are independent and can be employed simultaneously in heavy weather or in off-road situations.
