Sprint mode is absurd, I use only when I'm too tired to do a proper racing but not tired enough to go to bed. I just raced in Bahrain, I got a penalty after some guy tought my Force India is his braking pedal and in T4-5 some guy tought he was playing bumper cars and while he was pushing other guy, the other guy hit me. Of course both me the other guy got the penalty lulz.
