> why don’t cyclists ride in the middle of the street and/or slow down a bit
That is a reasonable question. If you truly want to know why cyclists generally don't ride slowly in the middle of the street you could always try doing it yourself.
> Have you ever seen cyclists in Dutch cities, they are simply stupid risk takers.
This is unsupported by the evidence of lower cyclist fatality rates in the Netherlands compared to the US. There is even some evidence that areas that have enacted mandatory helmet laws end up increasing the fatality rate per trip. (Primarily because the number of people riding bikes drops significantly and possibly because cars leave less buffer space to people wearing helmets.)
