Saudi F1 GP: DRS changes, quiz questions, yachts, and Perez's hopes.

The FIA has moved the third DRS activation point for the Saudi F1 GP to prevent drivers from braking erratically into the final corner and avoid "cat-and-mouse games". The Jeddah Corniche street circuit has also been modified for the second year in a row to improve visibility and address safety concerns. The ultra-fast circuit has been made slightly slower with the addition of a bevelled kerb through the high-speed left-right sequence at Turns 22 and 23, which is expected to reduce speeds by 50km/h.
