safety if the batteries are damaged in a crash is still an issue.


I would think the hazard somewhat less than gasoline.


The battery can produce it's own ignition source.


You have a point. While a source of ignition (sparking wires, hot
muffler?) is required to ignite post-crash gasoline fumes, it would
take an un-fused short circuit or significant deformation of a battery
to potentially ignite a lithium battery. Granted, if the crash occurs
as a result of fuel exhaustion, there is little fire hazard, while the
lithium would always be aboard.
