So many times I see close calls in which 2 cars try to change lane into a common middle lane in the freeway. Well, due to the slow acceleration of ICE cars, people have time to react to avoid major accident. For the 2020 roadster, the quick burst of acceleration may cause higher change of getting into an accident because the other driver do not have quick enough reaction to avoid an accident. I know that accidents like this or others do happen no matter what kind of cars you drive. But in the next few years, electric cars such as the Tesla 2020 roadster with its quick acceleration will likely increase accidents on the highway/freeway. Hopefully, there will be sensors in the future to diminish such incidents.
