#9 BINGO! You got it!!
I travel 43 miles to a relatives place and have to take the 101 to the 405. First off is the transition to the 405 which squeezes several lanes into 2 then has you go on a banked curve to the left then right then uphill. The right lane disappears further uphill forcing traffic to move over (crash bang). Coming back you are going downhill at 70+ with semis all around you. You must slow way down to 35 as you turn a sharp right curve then a sharp left curve to get back onto the 101.
Once on they have 1 lane for you as they have barriers up to protect you from the mad drivers in the other lanes coming at you at 70+ on a curve for several hundred feet before you can merge into other lanes!
Then there are the drivers who drive either too slow or way too fast and switch lanes with no warning or just merge expecting you to get out of the way.
The carpool lane is hardly in use compared to the rest of the lanes. Someone mentioned Wilshire blvd. I travel past that stretch and for about 2+ miles it is like you are on a washboard. So much for that $1 billion making the road better.
Oh and that 43 mile trip? It takes anywhere from 1 hour to 2.5 hours. This past Sunday it was 1 hour 35 minutes.
