On the E190 the autothrottle is a bit 'binary' in operation, but damped in its response. Therefore is regularly under/overshoots - and follows this with a correction. The ailerons are very powerful but to prevent excessive use, they have a very high, zero biased, spring "feel" force with no aerodynamic feedback. In my opinion, they are totally un-harmonised with the other controls. This gives a "rock'n'roll" ride in blustery conditions.
