It's a good time to implement fine based on vehicle owner income. Every km/h over 50 is that percentage of your yearly income (in addition to the base fine). 52 over is 2% of the owners previous year income. 150 over is your entire previous years income as a fine. That rapidly puts a damper on your desire to do a high speed run when you can lose your parents entire income. There is already some precedence for you being responsible for the consequences when lending out your car, such as insurance or a red light camera ticket following the owner.
I know VW lets you set a max speed with the OBD port. The downside is it is a one way street, it can never be raised again once you turn it down. That being said, I have no problem locking down a car that my kid drives to a speed I don't intend on exceeding.
Based on the vehicle owner's income? Even if the owner isn't the one driving?
