Yes, I think we'll have to agree to disagree about cycle lane design. But I'm not "expecting a car to sit behind another car turning right, instead of nipping into the cycle lanes". I am
expecting some cars to do so, and a corner of me even wants
them to do so occasionally when it's safe (to crush the glass to powder)! What I also want, however, is to make car drivers as self-conscious and as careful when they do so as they would be if they were breaking a red light... look to see is it safe, double-check, triple-check, make extra sure there are no cyclists anywhere near (as well as no gardaí) and only then go into the cycle lane. I think that's possible.
i think you concerns regarding left and right turns are over inflated.
I just know my behaviour as a daily cyclist for the past several years. For example... a junction where a main road going straight ahead has a left turn. The cycle track is on the (left hand) footpath. I want to go straight ahead.
(1) If I leave the cycle track and move onto the road I can cycle straight ahead, along with the cars - moving onto the road early enough before the junction that I'm not going to clash with any cars that are filtering left because I'm on the road before the left filter lane is created, and I don't go into it (so as I advance I am in the middle of the road, at the left of the 'straight ahead' lane). Once I'm past the junction I've to get back onto the cycle track on the footpath, which I do at the next place it's dished for a gate (I don't have a mountain bike). Fairly fast and simple. And as I said above, most drivers are pretty observant (as long as you do stuff far enough in advance).
(2) If I stayed on the cycle track I'd have to go as far as the junction, squiggle round a metal barrier, stop at the junction, wait for the cars filtering left to have all gone (and strictly wait for the pedestrian light, which is also the bike light, to turn green), get as far as the island in the centre, squiggle round another metal barrier, cross the other half of the road and continue on. (That's not even counting all the pedestrians that are standing in the part of the footpath that's marked as a cycle track, blissfully unaware that they're in the way.) The whole procedure is unnecessarily cumbersome and slow, and I don't do it. I don't see many other cyclists doing it either.
Hence my belief that if cycle lanes are unnecessarily awkward to use, however safe, they won't be used by any but the most timid cyclists. And the most timid cyclists won't cycle unless these ultra-safe cycle lanes are everywhere, which they never will be, so the lanes won't really be used much at all. And then the Corpo will say "What are we putting these things down for? Those irresponsible cyclists never use them anyway!" and won't realise it's because their design is crap.
I repeat – many car drivers are pretty good about watching out for bikes. (Most pedestrians are woeful.) What I want to do is to raise the awareness of all
drivers to such an extent that they're hyper-conscious about the dangers of entering a cycle track and make damn sure it's safe before they do so.
