As summer winds die down here's hoping one of the season's most ridiculous and unnecessary fads goes with them. Bird and Lime e-scooters are just the latest twist on the foot-powered Razor Scooters that took America by storm in 2000. Unlike Razor, which introduced electric-power models back in 2003, Bird and Lime utilize a subscription model instead of ownership. Bird, Lime and another competitor, Spin, have similar business strategies — namely to provide simple, cheap transportation for the "last mile."
