How do I get my stepfather to stop speeding while I'm in the car?

I live in a fairly large city and sometimes my stepdad has to drive me to my destination, But when driving hes always at least 20 km/ph over the speed

I live in a fairly large city and sometimes my stepdad has to drive me to my destination, But when driving he's always at least 20 km/ph over the speed limit and, it doesn't matter if i tell him to slow down and that he isn't just putting himself in danger, but also those around him, like me for instance. Please help me before he seriously hurts someone.
