Make 'em pay
If you drive your car and are about to get into the lane after a bus lane has finished and your rear left wheel touches that fat bus lane line - fine - no getting off
you go to a box junction, when at the time you start you can get your car across and then another on the wrong lane races in and cuts in front leaving you in the box junction - fine. And even if you have the dashcam footage to show that - Fine.
Let them have some of their own medicine
