Was driving on the Belt Parkway at night time near Sheepsheadbay area, when I saw Mr. Speed was cutting in and out of lanes. Got stuck behind three cars in each lane going relatively same speed, tailgates a car in the far right lane and then abruptly cuts into a merging lane on the right just as a car was entering...That would be Mr. Speed #2 because he got so offended he had to brake extra for a millisecond, he rev up to 80+ to catch up to Mr. Speed, cutting each and every other car that Mr. Speed had past...just to flash his high beams constantly when he caught up.
