My total commute is 52 miles round trip, so I usually drive 22 and ride 30. The 11 mile beginning and ending is very hilly and the roads are narrow and winding, so driving is better for that portion. The 15 mile riding portion is mostly MUPS/trails and fairly flat.

I have lots of options on where to park, all safe locations, and the ride can be shortened or lengthened, depending on the weather and traffic. Nice thing is, the riding portion of the commute is the most traffic congested, so riding is actually faster or about the same as driving. Tried the "leaving the car at work routine," but it makes for fewer, longer rides, rather than spreading out the riding evenly over the week.
