The motorbikes and motorcycles are reappearing, riding in large groups, speeding, passing cars illegally, driving the wrong way including in oncoming traffic lanes, doing wheelies through the park and along Madison from Manning to Lark and revving engines loudly at stop lights. Police officers in cars watch them pass without even attempting to pull them over (not talking about a high speed chase). The bikers know they have the upper hand. It's not a shooting--I get it--but it's severely impacting the quality of life in the park, for businesses on Lark and Madison, including with outdoor seating, and for residents throughout the city. It won't stop without consistent enforcement.
