I tend to see that many and more stupud things every single day. This morning there was a woman rushing to overtake me to get to a red light 30 yards away, stopping only after the third car to go straight through said red light in front of her dragged his heels a bit. Then there was a bus driver for whom 'give way to oncoming traffic' didn't mean him, a cyclist who hopped straight off the pavement inches in front of another cyclist who was riding along using both hands to text (how the heck they didn't both come off I don't know, but there was a lot of swerving and some swearing), a horde of cyclists using the pavement to get past delivery vehicles that couldn't get into bays so they just stopped in the (one lane, one way) road.
It ain't the time of year, its the general level of ignorance and impatience on our roads.
