We are bombarded by advertising constantly though, it was only a matter of time before it started making a regular appearance in games. Wipeout is just the tip of the proverbial iceberg, it won't be long before there is product placement in other games too or even full blown adverts and so long as they make money they will continue to be used. I agree the adverts should be more appropriate though for the medium they are presented in but this is all very new and hopefully will improve as they get feedback and learn from their mistakes.
