If you've ever been to a rock concert, you have been. They deal in these amperages all the time.

But not by pumping them into an auto sized object. That car is going to get very hot having that much energy pumped into it for 5 minutes. The cable size would be quite large, too. Of course, you can up the voltage in order to lower both the current required and the heat losses (as is done with high tension powerlines) but that presents other dangers.
