SIBS R148

The most hated Sunshine Island Bus Simulator bus line. R148 is a marathon shuttle operated by FTCC and REBC. It is the most hated route as it always appears on the daily challenge. Making players drive this route all the time and not having a chance to get other daily challenge routes that are more meaningful.

SIBS Player A: Heck nah, today's daily challenge is SIBS R148
SIBS Player B: NO WAY!!! When can I get to play N246, R370... It's been 3 consecutive days off R148
SIBS Player A: Addi should go run a marathon every time this route shows up. Who needs so many marathons, and it doesn't need to be SIBS R148 every time when there is one
