A reader sent in these photos of a collision between two drivers at Belmont Avenue and Sheridan Road on Friday at around 5 p.m. — more evidence of the speeding problem on Chicago streets. Our reader wrote:

Rush hour plus Cubs traffic departing the area probably made for congested circumstances, yet it seems excessive speed was a factor in this double-exit-the-roadway crash. Note that both vehicles are on the sidewalk [both are pointing slightly north]. The blue car is the area in which people alight the express buses that run up Lake Shore Drive to Belmont.

We put in an inquiry this morning with the police department about whether anyone was injured in the crash and have yet to get a response. We also asked the Department of Transportation for an update on the speed camera program, including when and where the first ones will be installed. This area would be eligible to receive automated enforcement under the 2012 speed camera ordinance.

One of the funny things about car crashes is that most people never see the aftermath. It’s as if nothing ever happened here. Clean up, move along, keep driving. The evidence that remains is much more subtle than an actual car wreck.

By the way, there were six other car crashes posted in Today’s Headlines, with over a dozen people injured.
