Knowing how to change a flat tire is a valuable skill, but drivers may find themselves out of practice when the situation arises. I will always remember my first flat tire. I was on a rural road and I was so proud to handle it all by myself. On the spare tire it was written not to drive more than 80 km/hour so I put my four ways flashers and drove half on the side of the road so it would be easier for other drivers to pass me. Well, don’t I get the finger by a 90-year-old woman passenger from another car! Seriously people? If someone has their four ways flashers on, it means they are having technical issues. They aren’t bad drivers trying to piss you off.
