One small point - that works only as far as you can see. For corners that you can't see through, even if you've been through them 100 times, it's safest to assume that there's a truck parked just beyond the furthest point you can see.
That's not a comment on being stupid or f*ing up, it's just advice to help in the future (worth what you paid for it). Since it's advice not criticism, I think I'm still allowed to say - I'm glad both you and the bike are OK!
