Do automobiles (car,bike,bus,train) require earthing?

  what do you exactly mean by grounding or earthing?
  There are multiple ways we can do that, ideally at home earthing etc is done in order to avoid the fault current not to effect the appliances.
  
  So as far my knowledge goes , car doesnt have the capability to generate high amount of power, only thing that might blow is head lamps.
  
  Who said tyres are not conductive? Most of the tyres have carbon which conduct;the static electricity which is generated by the car in motion is gone to ground through tyres.
  
  There are few modern types made from silica which is a great insulator, in this case people will get mild shock while exiting the car .

  Well, thats' a good question. Earthing in automobiles is usually done on the chassis. It doesn't necessarily have to be the earth to ground always. There's this interesting discussion which would give you the answer-

  @#-Link-Snipped-# : Earthing is very necessary in automobiles. The reason is the development of static charge in tyres when they rub on the ground. The staic charge may be high enough to create spark and might be a reason for fuel tank to catch fire. For small or light vehicles its not so important as it is in heavy vehicles.

  Well, because the faulty currents in electric circuits need a path. 😀

  Sir can any one ellobrate all the suitable reasons.
  As u told...sir bt wt about cars.only wheels are in contacts of earth.so hw can faulty current get ground.

  One more thng.i tooked a earth connection b/w starter moter and earthng cable which is connected to frame of vehicle.it is al abt a bike.
