The vast majority of cars on the road would still be drive-able after striking something like that (though many of them would miss it entirely dues to increased ground clearance). Even the vehicle in the blog post was drive-able, until it burst into flames... Striking road debris is _incredibly_ unlikely to cause a fire in a 'normal' vehicle. The placement and design of the fuel tank makes a puncture incredibly unlikely in the first place, and even in the event of a puncture, the most common outcome (by a wide margin) is that you run out of gas... There are obviously exceptions to this, but it's rare enough than it's a big deal (recall worthy) when a vehicle design lends itself to this sort of event.
