I`m 100% certain that the statement above is correct. Why? Because as a bicycle rider you get every day training in keeping yourself safe and alive, avoiding strangely behaving cars and pedestrians. You can probably say that the same is true for drivers and pedestrians as well, yet I believe that the bicycle riders are in a more dangerous position. The possibility for a pedestrian to be hit by an opening car door is rather low while on a bicycle you must always be ready to dodge such a door, plus a pedestrian usually moves relatively slowly, plus he usually is on the pavement. On a bicycle (in Riga) you don`t have a part of the road of your own - you`re either among cars or among pedestrians. The first ones can hit you and the second ones can attack you (luckily I don`t have much experience being attacked by aggressive old ladies yet I know that for many bicycle riders it is an almost everyday experience), so you become trained and you must always be ready to change your path in order to avoid a clash. And theoretically it should transfer to driving a car - that is in a car an experienced cycler should (probably) also be able to react faster.
