You can't reduce gridlock by taking out bike lanes. All those people on bikes, will be force to take cars, adding to the gridlock! The more people you take out of cars via different modes of transportation, the less gridlock you get.
Also, safety. Bike lanes make streets safer for everyone, including cars. Bike lanes help with people in wheelchairs.
Bike lanes help connect communities. Majority of people can't afford to own a car.
The few people who can afford a $100,000 3 ton vehicle of course will get upset when they can't get to their destination a minute or two faster than before. But those people in the bike lanes deserve the same dignity of being able to get to their destination safely. Removing bike lanes won't reduce gridlock.
