101 Freeway

I usually stay around SFO when I’m in town and I’ve got friends in south bay
101 is not the way to go. The road surface is uneven, making for an uncomfortable ride
Head instead for the 280, a much more scenic and generally less busy route

My rating is directly based upon how many unexpected butt massages occur. This is called the UBM count. This one tops the charts in number.
Causes of High UBM Count:
(-) Numerous potholes and cracks in the road.
(-) Attempts to cement over the cracks in the road, creating just as many UBM’s.
(-) Stop and go traffic from Mountain View all the way through Burlingame, which suddenly clears up and displays that there was no cause for the traffic to begin with. WTF?!
(-) At late night hours (close to 12 AM) they do construction, and all lanes tend to be closed except for one. Terrible funneling effect occurs along with slow speeds at less than 5 mph.
(-) Horrible drivers, most likely who are drunk, at all hours of the day. I am always getting cut off by people originally in slower lanes intending to spread the curse to the fast lane.
With 5 minuses, this rating should really be a ZERO but there is no such option.
Every time I take the 101 southbound after 10 PM, I get into trouble! Just last night, a trip that should have taken 20 minutes after a long day ended up taking 45 minutes. A minor accident on the right lane of 101 caused a complete standstill. Several police cars cleared the right lane so they could get to the accident — unlike this logical move, a lone ambulance decided to take the left lane. This caused a ton of cars to have to squish into the center of the freeway in a chaotic fashion.
TIP: Avoid this freeway at all costs. Even if it seems like it will take longer getting to the 280 or another southbound highway, DO IT. It’s totally worth it.
