There seems to be a loop hole to get great combo bonuses. Unlike the original Project Gotham Racing, this game allows you to go through the cone gates twice. You can go through either forwards or backwards, and hence build up your combo bonuses.

Geometry Wars mini-game
Go into the garage and push Y to enter walk mode. Go to the area where there is an arcade game next to some tool boxes and rims, to the right of the garage door. Push A to play the Geometry mini-game. To quit the game, push B, then A. The arcade game is usually in the north area of the garage.

Better driving and faster laps
Notice that on all tracks there are skid marks (darker tarmac) before turns and fast bends. When you approach the darker tarmac, hit the brakes and make a concentrated, cleaner turn. This will ensure a faster time and less mistakes.
When playing cone challenges, remember that it is all about the Kudos. If you look at the top ten ghosts of the Cone Challenge, you will see that people do not complete them fairly. They blatantly cheat by doing many, donuts, slides, and cone gates to accumulate the points. Even though this is not completely fair, it is also not that easy.
