This is already the case in MI. The Secretary of State (that is what we call the DMV in MI) has a schedule of "points" for each ticket and they may suspend your license based so many points over a certain period of time.

MI also enacted "driver responsibility fees" about 3 years ago which assess an extra fee from the SOS for particular penalties or combinations of penalties over short periods of time. These were modeled after the same ones enacted in NJ that saw a 24% reduction in traffic fatalities within a few years. If those fees are not paid the SOS will suspend a persons operators license. These fees are under attack right now by certain grassroots political campaigns calling for their repeal which is fine every person has their right to lobby the government. The real problem is activist judges refusing to uphold arrests of persons found driving on suspended operators licenses. In an article recently published by our local NBC affiliate recently court officials are quoted as saying they will refuse to convict people for this.....ridiculous. Here is a link to the article.
