In the 14 years after the Los Angeles Blue Line opened, Houston Texas was the largest US city without a light rail system. So at the beginning of 2004 it opened a 12.1 km system. However, it has had a collision rate with cars and SUVs of 25 times the North American average. The main reason is most likely that instead of having a dedicated right of way, it shares the road with normal vehicles.
The video shows some of these collisions with vehicles whose drivers are clearly thoughtless or impatient.
