god knows what happened today but approached a roundabout, put it into first and started to creep forward as i had traffic to my right. as i started to pull away i took my foot completely off the clutch, started to pick up speed when all of a sudden the car stopped then started going again (as if id slammed my foot on the brake)

from then on the car kept revving to 2000rpm whenever i tried to change gear. pulled into a carpark and suddenly started working as normal

anyone know what could have caused this as it scared the living s**t out of me
