What was he thinking?

This is really strange.

Somebody was riding a moped in Jerusalem with his 2 year old child. The kid had no helmet and was standing in the "floor" of the moped. I assume he was not driving fast.

A cop saw and stopped the guy. The guy pulls over his moped and takes off his helmet. He then took the kid off the moped and put him on the sidewalk, and before the cop could give him his ticket, he sped off on the moped.

the cop decided to stay with the kid rather than chase the moped. After a short amount of time, they identified the kid with the help of local residents who recognized him. The cop brought the kid home to his mother who refused to answer any of the cops questions about their identity, until the cop told her the story. Once she heard what happened, she helped out and gave the cop her husbands cellphone number.

They got hold of him on the phone and told him to come to the station. When they asked him what happened, he could not give an answer...

What was he thinking? When he put the kid down, did he think they would not identify him after he sped off? Was he going to just abandon the kid?
