The Mythbusters Mini-Myth about whether or not lane changing in traffic is faster than staying in one lane has its good sides and bad sides. For good, their experiment was carried out in real traffic, so there is no room for a bias fault or any miss calculations in a simulation. Also, the two cars ran at the same time so there was no environmental difference between the two variables. That being said, the experiment still needs some work, for example, they only have one data set, the experiment needs to be run more than once to eliminate luck ‘s influence. Another weakness is that the test only covered one environment, which was a San Diego highway in rush hour. There is also the problem of the driver used in the lane changing portion of the experiment. A more timid driver would be likely to make less lane changes than a more aggressive driver would, which would alter the results and effectiveness of that trial.
To be more inclusive, the test should be carried out on multiple roads and at multiple times, in different locations (drivers in Chicago are very different from drivers in Dallas, from my own experience), maybe use a four-lane highway, a six-lane highway and an eight-lane highway to get a more better feeling of where lane changing may or may not be faster. Testing different traffic variables could help get broader data as well, such as testing rush hour, traffic behind a car crash, and bottlenecking traffic. There is also the matter of the vehicle, a small car would theoretically have an easier time changing lanes than a longer car as it could more easily fit into the smaller gaps in the traffic of its neighboring lanes. To maintain reliable data, these trials would have to be repeated multiple times to help remove luck’s influence on the experiment. This is possible to carry out, even though it would be more difficult (an experiment of this scale would require extensive preparation), it would be much more expensive, in travel fees (to the varying locations), gas for the multiple trials, the cars themselves, and compensation for the participants.
Keeping all this in mind, the Mythbusters’ experiment will probably have to do for now as it would be difficult to carry out a full scale experiment and this topic isn’t exactly important enough for anyone to commit the time and money to work it all out.
