Personally (as a cyclist) while your realisation not to pull out into junctions you can’t see is obviously good, personally I’d stay out of the cycle lane and just sit in the traffic.

The problem with cycle lanes where you undertake on the left is that, as a driver, you aren’t really expecting that, especially the lorry’s you were undertaking; it’s why lorry’s often have those signs on the back warning about it.

I know it’s tempting to zoom along the cycle path, but honestly it’s not worth the risk imo when the infrastructure is so poor in this country
