I have some experience in this area
Pretty much walk into the show cause hearing and say " I accept responsibility for my actions, how long are you going to suspend my license?"
They will go through each one of your tickets/accidents and ask you details and you have an opportunity to give your side of the story. The MPI employees that work there are quite easy to talk to but also have todo their job.
If they like your attitude they will send you to the defensive driving course and keep your license on probation. if you have already been ordered to take the course in the past then you'll be looking at an automatic suspension.
Also, don't mention undue hardship by losing your license. Its not their job to factor in loss of employment or driving your kids to daycare, they will tell you the same if you try and take that route. If you truly have undue hardship they will still suspend your license then you can apply for a worker permit which you go before panel board of people and they decide if they will give you a permit and which conditions that get attached to it.
