It's interesting to note that the crash Concorde flight 4590 was also caused by road debris. When will they harden components that can withstand high-velocity impacts?

Apparently, Tesla has a new battery design in the works that has less of a chance of bursting into flames on impact. Until then drive slowly and on desolate roads with no oncoming traffic and you should be fine.

I'll be curious to see NHTSA's take on this issue, AnandY.

Speaking for myself, I would definitely not get into a car that catches fire every month through no fault of my own, let alone drive the damn thing myself. A good designer foresees future obstacles and sets in place measures meant to counter the same. The accidents simply mean that the manufacturers of the Tesla Model S electric car have simply not done their homework well enough.

That's a good point, Tool_Maker. I have a feeling that Tesla is now considering the possibility of a stronger plate on the bottom of the car.

@Battar: Trash on the road, while an example of carelessness on someone's part is nonetheless a part of road hazards all vehicles confront on a frequent basis. To design a vehicle incapable of handling them is irresponsible. Of course no engineer can foresee and protect against all hazards, but to have a high priced vehicle destroyed by a scrap of seems a bit ridiculous. How would this same vehicle handle buckeled pavement or a large pothole? Both of which I have encountered with a thud and shudder accompanied by a trip to a garage to have the front end realigned. I even hit a pothole, disguised as a puddle, big enough to flatten a tire and bottm out the frame, but there was no resulting fire.

Hot, indeed, GTOlover. When Boeing had its battery incidents last winter, NTSB investigators estimated temperatures of over 500 degrees F inside the battery pack.

As I have driven in various parts of the country over the last few years it has become obvious to me that there is a lot more road debris than there used to be in general, but certain areas look like distaster zones.  I believe that due to budget cuts at the state and local level there is no longer anyone charged with cleaning up these roadways anymore. So the debris just collects.  I can vividly remember an interstate near Detroit where for miles at a time the side of the roadway was so cluttered with debris (mostly shredded truck tires) it would not have been safe to pull off into the shoulder in case of emergency.

Damaged by road-rubble

It is unfortunate that these cars have been the ones to hit the junk on the roadway. I wonder if the drivers could have avoided the objects, or if they had time to avoid them. I once damaged a car to the point of having to replace it when the frame hit an object that I never even saw since it was covered with snow. It damaged both frame and the oil pan, and a bit of one connecting rod. So the Tesla is not alone in being damaged. The difference is that my car didn't catch fire, it just died.

Possibly some smart designer can start selling an armor plate to protect the battery from road-rubble wreckage. No need for Tesla to do it, let somebody else who is good at armor design create the solution. An armor plate air-dam to prevent objects from getting under the car where they can do damage. Bounce them sideways, not up.

Charles, seems this is turning into a hot topic!

I could not resist the pun:-)

Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
