When it comes to snail-paced speed, one car takes the cake for being the slowest of them all. With a turtle-like top speed of a mere 10 miles per hour, the Molassesmobile earns the title. Don’t expect any turbo-powered thrills with this one—it’s all about embracing a leisurely stroll on the road. While it may not win any races, it sure knows how to put the “slow” in slowpoke.
