With seemingly unlimited data collection all over the news recently, Michigan's government may soon buck the trend. On Wednesday, State Representative Sam Singh announced a bill that would regulate automatic license plate readers (LPRs) in state, including a mandate that collected data must be deleted within 48 hours unless it's evidence of "specific criminal wrongdoing," according to the Lansing State Journal.

Very few states currently have LPR restrictions, according to the LSJ. For instance, Vermont tosses data after 18 months, and Maine only holds it for 21 days unless data is involved in an investigation. (The paper noted Arkansas, Utah, and Virginia also have some restrictions). New Hampshire is the lone state to ban LPRs outright, and Iowa City made headlines this summer by taking the same approach on a smaller scale. But as Ars discovered when trying to access LPR data as a citizen, often times LPR data can legally be stored indefinitely.

Singh's bill is expected to be formally submitted next week and then considered within the state's legislative process (PDF). Currently, according to The State News, there are no in-state regulations in place to limit how long LPR data is kept.
