BAD IDEA …

If you were clever, you could design a shape-charge, like a super-sized claymore mine, into the tail gate of a truck. If you gave the driver bullet resistant glass and hearing protection, they could back up, fire the thing off, and drive away …

You could even design a near 360 degree deployment system into most modern trucks, and still give the driver a fighting chance at getting away.

But you should not do this.
