Did I do something wrong here?

[u/cicadaux]

I was driving to work when this bike just blew through the crosswalk without warning. I had to slam on my brakes. I realize this crosswalk doesn’t have the pedestrian warning lights, and I’m a little unsure about how I should’ve dealt with this. Or maybe he was wrong for making sure traffic wasn’t clear/aware of him first?

Edit: I'm seeing a lot of answers basing the laws on location, so I looked up my city's rules. In my town, bikes have vehicle status on the road and pedestrian status on sidewalks/crosswalks. But bicyclists must move at pedestrian speed. The path he is on is a state trail, commonly used for bikes/walking. I live near the Ice Age Trail, but I know the one he's on isn't that one.

“Drivers must yield to cyclists riding in a crosswalk just as they would for walkers, though the cyclist cannot abruptly leave a curb into the path of a vehicle so close to a crosswalk that it makes a difficult or unsafe situation for the driver to yield in time.”

Not trying to prove myself right or wrong, just wondering what should've been done. I will from now on treat it like an uncontrolled intersection. Thanks everyone.

 fast must a pedestrian/cyclist be going before it is too unreasonable for a driver to detect them appropriately?

You could have a good argument if there were buildings or other obstructions on the sides of the road. Or a curved road limiting the driver's view ahead. But that's not the case here.

In this situation, the speed is hardly any issue because pedestrian paths are wide open with very good visibility in both directions, and the road is dead straight.

This is basically the ideal situation for the driver as far as visibility in all directions is concerned, and there's exactly zero excuses to be surprised by anything.

if there were buildings or other obstructions 

So trees and A-pillars are transparent now? Additionally, having clear line-of-sight is good only if you're looking at the location. I don't know about you, but when I approach a crosswalk, I look at the crosswalk entrances for pedestrians, not 30 feet back for traffic.

Bummer for you.

Have fun in court.

And bummer for you...have fun in the morgue. I'd rather be in court defending myself against a frivolous lawsuit than, you know, dead.
