Disable low fuel alert for bicycles

[Giana]

The thread checking for low fuel does not exclude bicycles, and as a result, low fuel alerts occur incessantly for players riding bicycles. Ensuring that a vehicle is not a bicycle before checking if the fuel level is low and subsequently alerting prevents this alert from occurring for players riding bicycles.
