We rode behind David Hasselhoff and a Batmobile on a leg of 3,000-mile supercar rally Gumball 3000

Every year since 1999, hundreds of supercar owners have gathered together to drive around the world in convoy for the Gumball 3000 rally - a 3,000-mile cross-country rally that takes place on public roads. 

In between long drives, participants stay at luxury hotels and pop champagne at decadent nightclubs. Entry to the week-long rally costs around $50,000. And you need to provide your own supercar, obviously.

Business Insider was invited to take part in one leg of this year's 3000-mile rally from Dublin to Bucharest by Car Throttle - an app-based online car community dubbed "Buzzfeed for Cars"- which had entered Gumball 3000 with a Nissan GTR that was inexplicably wrapped in emojis.

We were only with the team for one day - from London to Kent on day three - but it gave us a flavor of the event. Inside the "EmojiTR," Car Throttle CEO Adnan Ebrahim filled us in on what we had missed.
