The last electric car race that I attended with my sons was more than 
a year ago.
Some of the big speed guys were using Lithium and Li-po batteries.
One of the lithium equipped cars hit something out on the course and 
punctured the case. About two laps later it the car was just 
enveloped in flames, the heat was intense enough to crater the 
asphalt that we were racing on. Several of us threw buckets of sand 
on it to smother it, but still took about two hours to cool off.

Also there was a loud bang in the pits, when one of the guys running 
Li-poly packs had one explode. Fortunately he had the pack in a fire 
& explosion proof box, so only the pack was destroyed.

but that certainly made me wary of lithium batteries
