Experts in the psychological area found that electric car drivers are happier due to the sound of the engine, it turns out that drivers of this type of vehicle feel much less stress than those driving cars with combustion engines.
The experts who have developed this research clearly point to the noise as partial culprit of the stress behind the wheel. Being a vehicle without combustion engine, there is much less noise inside and therefore you can concentrate better on driving and stay calm.
The objective of the study was not to prove that the drivers of electric cars are happier, but to check the possible differences at psychological level of piloting one type of vehicle or another. The surprise was when the results were so different depending on the type of car engine.
To take the data, Electroencephalograms were performed to London taxi drivers while they were driving, thus measuring their brain activity permanently throughout their working days.
