If Richard accidentally hit Emily's car when he saw her talking to Simon...

Then why didn't he immediately say, "Oh my god are you OK??? I'm so sorry!" That's what you do when you think you may have accidentally done harm to someone. Instead, he only asks if she's OK after Simon asks. Then he practically drags her out of the car and into his. This may be an unpopular opinion but to me, it seems like he hit her car out of jealousy, anger, and spite, and not by accident.

And then to make matters worse, he tries to blame her for it by saying that when you pull up to a valet stand "you don't dawdle." Like Richard slamming into her car while she's in it is somehow Emily's fault? Um no.

This is a real low point for Richard, IMO.
