text: There are laws that prevent driverless ars being tested because the government believes that these cars are dangerous to pedestrians and other vehicles. If the government believes that these cars are too dangerous for the roads then why do certain companies want these cars to be on the roads? Car companies want these cars on the roads because they would be expensive to buy and they would make alot of profit if they where able to sell these types of vehicles. They are cars out now that have driverless features such as parallel parking and automatic breaking but these features have failed many times. Driverless cars are driven by computers which can malfunction like all computers do at one time or another.
