text: Another factor that comes into play with smart cars is how it compares to humans. Lawmakers say that the best safety is from an alert driver. Today there are a lot of people that aren't so alert, such as people that are intoxicated or just tired. Wrecks as we know are a big issue and a lot of them come from people that aren't alert because of them drinking or using other drugs, now I'm not saying this is most people, but quite a few. Another thing is roadrage, people tend to get mad behind the wheel because of slow traffic or other causes thar cause accidents or incidents that cause the law to come into play.
