The mugs I use to bring the java to work are insulated and (not quite hermetically) sealed. You flick open the sipper with a thumb lever. You can still burn your tongue I guess, but spillage would only happen if you were dumb enough to try and (literally) drink and drive. They do not, however, have a magnetic base - thus the CD bucket storage in the saddlebag for now. My "commute" is about 6.5 miles and takes between 10 and 15 minutes max, and typically only has a few short stops so there is little actual value (other than the joke) of having access to the beverage in flight.
