I'm not very good at traffic levels and I did play and gave up but then I revisited it. I was thinking wow the exit is guarded pretty good so how can B do this WITHOUT tricks. Spoiler The quick back and forth wasn't very stable but I got it on the 4th attempt.
Couldn't solve this before, but got it now. @gmacpro There is a clean solution with a controllable slide-up, slide-over and drop. No quick sliding with multiple sliders required.
Ok. It wasn't intended to do this that quick so B falls. There is more elegant and clean way to do this. The title was about srossing the barrier only. Still thanks for completing @gmacpro, but if you have enough time to mess with this traffic, then I think it's better to find intended solution.
@Block builder very glad you've solved this in intended way without dropping! Really messy traffic, isn't it? Thanks for completing!
Curious traffic puzzle. I honestly don't know if I solved it in the designed way as I saw many possibilities. But it was fun. Thanks for sharing!
