Hyundai's sister company Kia has given the world an interesting insight by coming out and stating that 20% of all relationship breakups are due to driving habits of either partner.

Research shows that driving with your 'other half' is the ultimate test of love, with one in five singletons admitting to ending a relationship after arguing with a partner about their driving. So why not find out how suited you are in a car before you start going out? - Kia UK

Right. I think the more important point that Kia has obviously overlooked, is that 1 in 5 relationships end when the couple buy a Kia. Nevertheless, the obvious publicity stunt led Kia to devise a plan to match up 20 men and 20 women after doing a compatibility test... when paired in a car. Kia said they will see how the new couples progress.
