It has to do with at what percentile of wary and being good drivers we think we are. Also abduction is not the only risk for children.

I believe that often than not people do the right thing, if it something done in mass there is a reason for it and it is just hard to pin point the reason.

There can be social reasons for it, also we don't know if there is some implicit higher chances of getting abducted for kids who get drove to school. Like them walking to school will increase the chance of them abducted.
