Hybrid/electric vehicles have a high probability of success in the future, and conventional cars will slowly disappear. Hybrid cars have more than one power source, which saves gas. By saving gas, individuals will be able to spend their money on other things. Hybrid cars also require the same economical maintenance as a modern conventional car. By having the same prices for maintenance, people will not have to invest more in the car of the future. The best part of all the comparisons is that the hybrid vehicle will reduce carbon monoxide in the air by as much as 25 pounds. By switching to hybrids, there will be cleaner air to breathe for generations
