The trunk open button on my remote sits "high" and it often inadvertently gets pushed in my pocket-sometimes at inopportune times.
In this particular case, I had apparently hit it somewhere in the process of getting the keys out of my pocket. When this happens, the trunk doesn't actually open all the way, but just pops up a little bit. Vibration from driving will usually open it up all the way.
Generally, it's not a problem, as I can just pull over and shut it. I don't normally have a stack of servers in the trunk
I also managed to miss the warning on the instrument panel about the trunk being ajar in this case, as I was trying to make sure the servers stacked in the back seat(I had a bunch of these things at the time) were secure.
"Gimme fuel, gimme fire, gimme that which I desire" and you mash the pedal to the floor. BANG! What was that? OH CRUD THE SERVER IS IN THE MIDDLE OF THE ROAD! Son of a Bunn Special!
