I feel very sorry for the cyclist and for the people who were in the shop at the time. Must have been terrifying.
But... years ago, a driver lost control of their car and drove into the front entrance of the building I used to work in. No other car involved. It was a situation involving accidentally pressing the accelerator instead of the break, and I think a great deal of panic. The driver did the wrong thing in the circumstances (and yes, I think they should have lost their licence over the accident, I don't know if they did) but none of it was intentional.
If she'd got all het up and upset having an altercation with someone, I think it's not outside the realms of possibility that she put her foot down a bit more than usual in order to drive off, lost control of the vehicle, nearly hit a few people and ended up hitting a shop. She may have tried to run him over, but I really hope that wasn't the case with 5 children in the car.
Just very glad that no one was hurt.
