So I was riding along Banks Ave and I let a car go in front so I wouldn't be holding it up.
Then I proceeded to cycle very fast behind the car so I wouldn't be stuck in the middle.
My logic was, I'd rather be near and behind a visible car, than in a random gap somewhere with a car coming up behind me.
However, whenever there was a speed bump, the car would slow down almost to stationery to go over the speed bumps and I ended up getting quite close each time this happened.
After a few bumps, I noticed the driver did a finger waggle that I could see in the rear view mirror.
I don't know if it was directed at me, but in hindsight I realise it was probably rude to tailgate a car, regardless of how slow and safe it is.
