William and Kate loved cycling. One week ago, they decided to do a round island cycling trip and finish off the trip with their favourite hawker food at the East Coast Lagoon Food Village. While they were riding on the East Coast Parkway (ECP) towards the Food Village, they were stopped by traffic police. The traffic police told them that they were breaking the law and could be fined up to $2,000 or jailed for up to six months.
