What is a "car phone"?

A car phone is a telephone installed in a vehicle that allows the driver or passengers to make and receive calls while on the road. Car phones were popular before the widespread use of mobile phones, offering a way for people to stay connected while traveling. They were usually connected to a car’s electrical system and used a special antenna for signal reception.

Today, many vehicles come with Bluetooth connectivity, allowing drivers to use their smartphones hands-free.
