One of the promotions Sega Europe/Dreamarena did for MSR was this Speed Challenge competition.....
Basically this was a 'fastest lap' competition over 3 courses (one in each city) using MSR's headline car, the VX220/Speedster. After getting a fast time, you would then upload them to the leaderboards within Dreamarena. Here's a picture of the London ranking (scanned from ODM #17):
Frustratingly you are forced to drive with automatic gears and ABS on, however those winning players still managed some spectacular times:
The London Challenge (St James's Park/Long/Parliament Street South II)
Best lap: 1'10.422 set by benvollo (France)
The San Francisco Challenge (Financial District/Medium/Market West II)
Best lap: 1'01.327 set by Sirus (UK)
The Tokyo Challenge (Shinjuku/Long/Higashi-Dori Kita II)
Best lap: 0'56.034 set by Manasel (Spain)

Here's an interview with the San Francisco Challenge winner in ODM #18:
2023 update: A commentator who took part in The London Challenge told me about the watch they received as a runner-up prize. It was a 'Swatch New Chrono Overdrive SK413' that was released circa 1998. A picture is below. In my opinion, the runner-ups received a better prize than the winners (who got a Dreamcast wheel).
If you can get your Dreamcast online and wish to challenge my times, the above Time Trial files can be obtained at: https://dreamcastlive.net/metropolis-street-racer-dlc/
August 2023 update: I have now managed to beat the competition times using Speed Challenge rules (automatic gears and ABS). Please see the following link for more information: https://msrdreamcast.blogspot.com/2023/08/my-speed-challenge-quest.html
