Even though biking is very convenient, it is not the safest mode of transportation. In 2015, there were 818 bicycle fatalities nationally attributed to incidents with motorized vehicles which was a substantial increase from 2014 in which 729 deaths were tallied. 70% of these deaths occurred in urban areas like Boston. Bikes are often overlooked by cars which are two tons of metal driving right beside twenty pounds of unprotected tin.
It's also true that cars have been prioritized over bikes in the late 20th century; many highways were constructed and land set aside for parking lots. Now, there are as many as 210 million drivers while there are only 67 million bikers in America. Cars are the most used source of transportation, despite the high costs.
Bicycle usage was drastically decreased with the making of cars, and because cars are seen as better vehicles for long distance travel as well as being safer, they are being used more frequently. Though bicycles are being used slightly more over the past ten years, they are not used nearly as much as they should be in a healthy world.
Overall, the biggest problems for bikes is definitely cars. Their overall safety concerns in the streets are the ultimate concerns of the public, yet the public's love for cars is almost impossible to sway. Cars constantly crash into bikes that share their lanes, and can only feel a bump. It's almost as if bikes don't stand a chance unless you're a professional biker.
