Also, I could be wrong about this - but you have to move fast, if you do the last step immediately, it seems you can beat the block on the seat. If you wait a second or two, it's blocked.

What I just said above could be entirely wrong - as I did this multiple times in slightly different ways until it worked, so I'm not 100% certain what I did.

Now I'm worried that at some point the system will realize what I did and punish us by moving us both to middle seats.
