You're very unlikely to get any trouble from him. Firstly the people you have reported it to are not going to be distributing your name, and even if they did, it is very unlikely that he would follow through on his threats once he is not in his van. People are in a different more aggressive place when they are driving which does not necessarily translate to their out of vehicle persona. But he still needs to be reported and ideally banned from ever driving again - if he cannot handle a vehicle without endangering other people, then he should not be put in that position. Unlikely, but if he gets removed from driving duties at his current job, we will all be a little safer.
