Hiya,

Some more items for the list:

* When using a composite wheel/tire -- tune the (regenerative) suspension to work with said wheel/tire. This could gain even more energy, since very little would be damped by the tires.

* Multiple car door latches could be used to increase strength & safety of the chassis -- helps to further reduce weight, increase strength & rigidity, without requiring an unusual entry method.

The Loremo and the VW 1L car both use unusual entry doors (basically the roof opens up), and having multiple latches would let you keep more conventional doors, but not give up the overall strength of the chassis, and/or save weight.
