Unlicensed drivers still drive because it is a necessity in many places, so they risk the jail time in order to continue working and other activities of life in the modern world. That's taking away driver's licenses is often an unjust, futile punishment creating more problems .

Rarely, if ever, has threats of "increasing jail time" or other harsh negative consequences actually prevented crime or changed human behavior. Rather, such measures only create more problems and more expense for citizens and the public institutions. That's because they too easily and swiftly interfere with people's ability to lead productive lives (taking away driver's licenses from those who are not repeat offenders is an example, as are escalating fines for low-income people). It would be smarter to address the underlying problems people are dealing with that lead them to break laws in the first place, as well as look at whether laws are broken because they shouldn't be laws in the first place.
