It's not easy to stop them. Imprison them? For how long? I read somewhere that car makers will be required to fit alcohol interlocks to all new cars sometime soon. That will be one solution. So drunks will drive older, less safe cars. There is no conspiracy. Governments hate road deaths. It's messy, inconvenient and easy to blame governments for "not doing enough". Of course, ensuring that children know that there are consequences to bad behaviour would be a start. That's not PC these days. So cars have to be turned into mobile padded cells to prevent people from hurting themselves and others. Eventually, no one will be anything but a passenger in their own car, if indeed car ownership remains a thing.
