Speed Demon?

Alex feels the need, the need for the speed.

And he feels this need in such a pronounced fashion that he felt the need to update his status from his PHONE. This need he feels obviously hasn't manifested itself to anything real as otherwise he'd a) be going too fast in some sort of speedboat/posh car/airplane to update from a mobile or
b) would be off his tits on cheap speed.

I'd prefer the latter.
