How do you use a cycle lane with vans in it?

Water Lane in Cambridge should be a good little cycling route. Its well off the road and protected by kerbs, you can validly criticise the design for being way too short of course, but in itself it should be great. Decent width and fully segregated.

But it is always full of cars and vans. Every time I'm there.

Once in a while I've taken a photo of this, such as these ones this morning...

Now I was going to use those photos to highlight that I believe efforts by campaigners and local councillors to get parking enforcement there have backfired spectacularly - rather than block the cycle lane the van driver there is blocking the pavement almost entirely. Look at the top picture - you MIGHT get a wheelchair down the side of that but you probably wouldn't. You certainly shouldn't have to fear not being able to get where you're going because of parking like that.

Anyway, after I took the second picture I mounted back up and started to ride... for no distance at all before this happened: 

Yes, thats right, a van reversed out of a driveway in front of me and rather than going in to the road he the driver decided to drive at me. I stopped, dismounted to one side (old posties bike today so its a step through frame - you can't straddle it and support it you have to get off and hold) and got the phone back out. Thats when the driver temporarily stopped shouting obscenities at me. 

I video'd the next bit. 

So he wants to get off this guys driveway - by driving down the bike route. He doesn't want to go out on to the road he wants to exit by driving at me. I can't fit down the side of him, I'm on my monster old Posties bike and I can't hop up on the pavement on the left to get out of his way very easily (and that would be illegal). So what the hell does he want me to do? 

I stopped filming to go on, he pulled a little back on to the driveway and continued shouting obscenities at me. 

I'd report this to the Police but they routinely refuse to deal with far, far worse. Parking enforcement isn't working - clearly the mototists who park there don't give a damn. And if we try to use the bike lane we risk being driven at by motorists breaking the law. 

What the hell is the point?
