Can I be really pedantic and point out that the thing you lot are all talking about is the tonneau cover? The tonneau is the thing you sit in, aka cockpit. Strictly speaking, we should only be referring to tonneaus and tonneau covers when talking about 4-seaters, as really the tonneau is the bit the passengers sit in.

I use mine pretty much all the time when driving. The only time I leave it at home is in the winter, when it's more likely I'm going to need to put the hood up quickly. Mine is a three-zip version, so you can have the side on in cold weather, and be really snug.
