Crazy Taxi

For this trophy you need to clear stages S-3 and 3-S. First you need to clear the stages 3-1, 3-2 and 3-3 to unlock 3-S, you'll also need to clear 1-3 and 2-3 to unlock S-3.

3-S Crazy Zigzag 2 Rule
This one looks like another tricky one but you can make it a little easier on yourself. Instead of trying to drift then come to stop right on the edge, use dash to get up to the white line just before the corners, then brake and slowly and carefully turn into the marker whilst turning to face the next marker, then dash to the next marker and repeat to the end.

S-3 Crazy Party Rule
This is a little tricky but once you have your route mapped out, it just takes a little practice. The route I chose was as soon as it starts (dash) turn left and go all the way up the spiral, pick up passenger 1, then straight off that spiral I'd get the passenger in the phone booth left of the ramp, then straight across to the passenger by the boxes on the right of the ramp, then straight down the car park to get passenger 4, then up the second spiral to get number 5, then jump off and head towards the ramp. You need to have enough speed to make the jump; as long as you do and make it, pick up the last two passengers and drive to the marker. Be careful right at the end as you have a lot of speed at this point and can easily drive off the edge if you hit the final corner too fast.
