It's a question that has been jamming the minds of motorists for as long as HiQ can remember and now, we can finally provide the answer.
In a survey to find out the most popular driving anthem of all time, The Who's 'My Generation has risen to the top of the charts.
We commissioned a survey to discover which track is the most enjoyable to listen to in the car, and Roger Daltrey and Pete Townshend's inimitable sounds were deemed the most popular amongst drivers.
Meanwhile, a separate poll to find the most popular album put Pink Floyd's 'Dark Side of the Moon' at the top of the charts.
In a top 10 singles list dominated by rock and indie related artists, Queen's 'Don't Stop Me Now' is second in the chart, with Steppenwolf (Born to be Wild) third, The Prodigy fourth (Firestarter) and David Bowie fifth (Heroes)
Marketing manager Geraldine McGovern said "We didn't know what to expect when we put the question to drivers. We had a lot of different suggestions, which we are well used to, as we stock a whole host of different tyres at our forecourts!
"If I said I had heard of all of the entries I would be lying, but we thought The Who was a good choice which we weren't unhappy with!"
HiQ can lay no claim to uplifting music keeping motorists alert when making long journeys, but the network does encourage drivers to take a break if tired, and to plan every lengthy journey in advance.
Geraldine added: "Participating centres are all offering free vehicle health checks to ensure that cars are in good, safe working order.
"These eight-point checks are offered free of charge in an attempt to assist motorists wherever possible."
