This, for the large part, make them unsuitable at this time for vehicle use.
Ooooh, that wouldnt be good "floor it, and burst into flames"
The charging part would be a big factor too. run it low and charge for twice the amount of time, I would guess those would be LiIon cons..

I don't think that's accurate.
Point 1: Recharge rate.
My computer runs for 2.5 hours on batteries and only takes 1.5 hours to recharge. My cell phone, likewise, has a 3.0 hour talk time and a 2.0 hour recharge. My iPod runs for 7 hours and recharges in 3. My PDA runs for 8 hours and recharges in 6. So... What I have observed from my lithium ion applications is that the recharge time is only 2/3 of the discharge rate.
Point 2: Battery Safety
You can eliminate the thermal runaway problem by implementing a large array of small batteries instead of a small array of large batteries. Sure, that would drive the manufacturing cost up a *little*, but you'd have a stable power source for the car.
Hope is like a candle held against the night.
