In the morning I ride toward the rising sun and I sometime wonder if cars can even see me despite the flashing lights and various reflectors. The same equation could be applied to my ride home.

Bike Lane:
-Speed limits of 60mph in areas mean cars are going past you rather fast (can be unnerving).
-Visibility may be an issue with drivers.
-Most direct route (generally takes 10-15 minutes less time).
-Least number of obstacles.

MUP:
-No cars to contend with.
-Takes longer due to being less direct.
-Takes longer due to contending with joggers, walkers, and slower cyclists (beach cruisers mainly).
-More relaxing ride overall.

Would you take a bike lane all the way to work or an MUP? I am torn on which route to take...most my commutes have been at night till recently so morning commutes are throwing me for a loop.
