They’ll need to have a fire station every 10 miles along the roads these things ride on.
The Federal Railroad Administration has hot bearing detectors along sections of track. The are present to alert a train crew of a bearing burn-off. A lower tech approach uses embedded stink bombs on the bearing that light off when the bearing burns. If you don't detect and stop, the bearing burn off can cause a derailment.
My research project put bearing temperature detection on each bearing adapter and used an 802.11b network with an OLSR mesh network to send a warning to the locomotive engineer. Continuous monitoring instead of fixed locations that often miss the burn off before it causes a derailment. My program evaporated the morning after Obama was inaugurated in January 2009.
An 11,000 pound lithium incendiary bomb. The fireball will be spectacular.
What is the cost? What is the cost of a battery replacement?
How long to charge and at what cost? Trucks are parked everywhere and not at a charging station for hours or days.
If in an accident the battery pack cannot be repaired.
One bad battery cell equals a big bad fire and a dead trucker.
