When inserting the Drive, jerk it from side to side once to make sure it is solidly locked. You can unlock either side by dragging your heel back over it. When done on purpose it makes for a very fast removal of the Drive (you can even lift the Drive out with your feet if you're so inclined). When done accidentally on one side The Drive will eventually jamb as you now know.
These over-center springs are designed to hold the lever in whatever position it is placed in -- that's what makes the insertion and extraction so quick and easy. The spring only needs to hold the lever positively in position until tripped and already has quite a bit more tension than is actually needed for that purpose.
The Adventure / AI has the shallowest drivewell so the levers ride higher than other models. I haven't accidentally tripped a lever (yet) but have managed to jamb the Drive by screwing around pedaling with the Drive unlocked. But I used to often inadvertently unscrew the old starboard cam lock on the previous system when sailing -- this is a huge improvement as it allows your foot more room without interference among other things.
If the Drive unlocks, you can usually feel it rock for awhile before it jambs, once you become sensitive to the feel. You can then relock it with your heel, verify the lock by wiggling your feet and you're good to go without even leaning forward. BTW, if the Drive does jamb and you can't clear it on the water, the Drive will still operate on a restricted basis to get you back if necessary.
It's a small cockpit -- you have to be careful where you put your feet and which end of the mainsheet to grab after setting it down!
