That's not how nuclear batteries work. The one I linked is radioactive carbon 14 formed into diamonds. That'd be fine in a crash.

  It also has power density on the order of 1 µW/cm^3 (= 1 W/m^3), which is incredibly low. An entire truckload of those batteries wouldn't even be able to power the truck's headlights.

    That's a good point.
