The middle finger is perhaps the most used sign on the roads, but just in case you want technology to do that for you, “The Hand” could very well be your proverbial best friend. Apart from the middle finger, you also get the choice of using many other animated hand signs, most of which aren’t insulting. We don’t really need to be angry drivers on the road (for sometime at least) and for once, we could send out a ‘peace’ or a ‘you rock’ gesture. The device can be operated by a remote control, and there’s a total of seven signs you could use. The accessory costs $40.
