I'd say, that the bot lane is so rarely "instalocked" becasue it is the hardest lane to play both as a support and adc aswell:

Top lane is usually a bruiser or tank which can just stay top and farm, does not get focused hard in teamfights, gets a lot of survi etc.

Mid is the shortest lane, hard to gank if u have the least warding awareness, mid champs usually have good early game and some cc  to defend or attack if needed, which makes playing it easier...

Jungler is jungler, as long as u don't die while ganking or get executed at red by counterjungler beast (ok, it's not all that simple but, u know what I mean) u don't have to worry about it. Junglers are usually also tanky with some survi and are not considered a huge threat by the enemies...

ADC on the other hand is really squishy, usually have weaker early than others and the most important thing: players has to cope with the pressure from their team to "carry" them in the late game which means getting fed in early-mid, which on the other hand puts the pressure on the support that is responsible for carrying the carry through the lanning phase and setting up kills for him, defending him from dying to ganks and skirmishes, warding the river, objectives and the whole freaking map, whereas top and mid just focus on their own lanning (and gank occasionally) and that pressure is imo the reason why nobody wants to pick bot lane.

Sorry for DA WALL... :P
