In that case, if the car crossed the line dividing the vehicle lane from the bike lane, the vehicle would be at fault. Of course, as with ALL collisions, it may become vital to actually determine the point-of-impact (POI) to determine who actually struck who.

Always wear a helmet, use hand signals to indicate turns, and stay visible by wearing bright clothing. Be alert, obey traffic signals, and avoid distractions like using headphones.
A bicyclist riding downhill has kinetic energy, which is the energy associated with motion. As the cyclist descends, the potential energy from being at a higher elevation is converted to kinetic energy due to the increased speed of the bicycle.
To rid as such isn't against the law, but there may be rules against riding unsupervised in traffic.
Vehicle riding saves time. Bigger vehicles can transport more number of people from one place to the other. Disadvantages include accidents while riding and high intensity of traffic leading to increased pollution, contaminating the air.
