I live a few blockss from the entrance ramp where this took place. The ramp for the gas station is very narrow. I still cant see how someone can crash into the pump there though unless they had lost control of the car and was going extremely fast on a highway that is rural and quite slow compared to a major highway. They had to be going over 80 on that ramp to lose control in that manner.
I doubt it was terrorism in nature, just an unfortunate accident.
Thanks for the local input.
