Car2go just became slightly less viable as a replacement for owning a personal ride. The rental service has introduced a variable-rate pricing system that, for all intents and purposes, will raise prices for customers starting on September 9th. The base per-minute rate has dropped from 45 cents to 35 cents, but that's only at "times, locations and days" when there isn't much use. In practice, you'll pay up to 49 cents when it's busy. By-the-hour use, meanwhile, is unambiguously more expensive. Where a two-hour session used to cost a flat $29, you're now paying up to a third more ($40).
