Role/Roll reversal.
The F4 used to (still does - any still flying?) have a rudder shaker to remind you to roll the aircraft with rudder to prevent roll reversal at low speed. Perhaps airliners should have a rudder shaker to warn you are not taking off at the right intersection!
But seriously, a wrong intersection / runway incursion warning system should be a priority for the next life saving aviation gadget. It's not rocket science - the infrastructure is alreadt there. It's just software.
