I think it's poor form not to clear a junction quickly, as it can cause problems such as this. Sometimes drivers just linger due to distraction when they should be making progress, other times they've entered a junction when their way is blocked.
But ultimately I fear the responsibility lies with the rider, you have to allow enough margin for error such that you can avoid a collision in the event if the unexpected.
Do sympathise, it's a mistake we could all make, and I'm glad you and the bike are okay
Why did he stop?
