Watch: Narain Karthikeyan drives surprised customers as part of Ola Cabs campaign

Imagine you order a cab on a car service app and wait for it to turn up. You're probably thinking about how long it will take the driver to get arrive and then, how late you're going to be.But imagine your surprise when the car does arrive and the driver is actually a Formula 1 driver! You would either hope for empty roads and the ride of your life or probably just cancel your appointment. Either ways, it makes for a wonderful surprise and a selfie to remember.[caption id="attachment_2428430" align="alignleft" width="380"] A screengrab from the video[/caption]That's exactly what Ola Cabs did in a special campaign called 'Ola Prime Time'. To mark the addition of new cars to their fleet, Ola Cabs decided to surprise a few select customers by having Indian racecar driver Narain Karthikeyan drive them around. To make things more camera-friendly, they had comedian Abish Mathew  (remember him from the AIB Roast?) travel along with Karthikeyan and the customers.Needless to say, the select few who got to be driven around by an F1 driver alongside a YouTube star, were more than happy. Mathew seemed to have a ticking score with Karthikeyan counting how many people recognise the internet personality before the sportsman.  Karthikeyan seemed to enjoy himself as well, and even asked "Do you want me to scare the sh*t out of them?" Thankfully for them, he didn't!But  Karthikeyan isn't the first F1 driver to get behind the wheel of a cab. Back in 2007, F1 legend Michael Schumacher did it for real, taking over from a cab driver in order to reach the airport in time.Watch the full video here
