Texas Transportation Code
551.104(b) A person may not operate a bicycle at nighttime unless the bicycle is equipped with:
(1) a lamp on the front of the bicycle that emits a white light visible from a distance of at least 500 feet in front of the bicycle; and
(2) on the rear of the bicycle:
(A) a red reflector that is:
(i) of a type approved by the department; and
(ii) visible when directly in front of lawful upper beams of motor vehicle headlamps from all distances from 50 to 300 feet to the rear of the bicycle; or
(B) a lamp that emits a red light visible from a distance of 500 feet to the rear of the bicycle.
2. Normally a group ride tries to keep the group together through traffic lights, which is obviously what they were doing, even if the light turns red. The group is sort of treated like one large vehicle in this instance.
Each bicycle is an individual vehicle, and required to obey traffic laws as such.
3. You cannot stop a bicycle very fast,
Since when? I can definitely stop my bicycle in a much shorter distance than any car I'm aware of, and a fair amount of my riding is on slick, polished concrete, not rough, high-traction asphalt. Bear in mind that the transportation code also requires that 551.104(a) requires that a bicycle be "equipped with a brake capable of making a braked wheel skid on dry, level, clean pavement."
