Which is absolutely stupid because a) any applicable insurance coverage is gone in the case something happens and b) if the authorities catch you things go from bad to worse.
A DWI doesn't stop some people with some serious problems. I always hear of someone being charged with their fifth, sixth, seventh, etc. DWI charge. Things are getting better, though. In the last few years, they now put a breathalyzer in these people's vehicles that requires them to use before the vehicle will start. If they are over .10 BAC, the vehicle simply will not start. Of course, then some people just get other people to blow into the breathalyzer

. Or they just use a different vehicle. Alot of people with several DWIs, I doubt even have insurance, they don't care....
People with a DWI, still have access to a car, because some NEED them to work. If they can't work, they can't pay for the fine(s), and with no money, they would all end up being a burden to society (welfare, unemployment). They get an 'occupational' license that is supposed to only be used for driving to and from work and to run some errands, and can only drive during certain hours, usually during the day unless they work a night shift. Obviously there are people who violate the conditions of their occupational license.
And now, the amount of jailtime spent increases as you get more charges. First offense doesn't require any jailtime (unless you can't pay the fine, then it is 30 days), but the second charge is a mandatory 6 month jail term, IIRC, here in Wisconsin. A person with several DWIs would spend several years in jail, whereas in the past (several years ago), every charge got the same sentence.
I agree with the more crimes/the harsher the penalty, as alot of people can make a mistake once (if they hadn't harmed or killed anyone), the big question is whether or not they learn from their mistakes. Obviously if they get a 2nd and 3rd DWI, they haven't learned and need to be locked up.
A DWI is a misdemeanor, but I believe I just read that in Minnesota, they are now making multiple DWIs (3 or more?) a felony.
