In-Car Comfort Without Opening Windows
The fact that drivers do not have to stop to take tickets and make payments means there is no need to open and close their window.
This brings many other benefits.
For example, on wet and windy days the driver can be freed from the discomfort of having rain blow inside their vehicle when paying.
Meanwhile, comfortably conditioned vehicles do not have to fear cold or warm air escaping.
In addition, drivers do not have to worry about exhaust fumes from the vehicle in front, thus making ETC a system that protects the comfortable in-vehicle environment.
