Not everyone can live without that red mark in the ledger, but we'll help you find out if you might be a candidate. Where I live in Atlanta, the necessity of owning a car is highly subjective. In some areas, it's not possible to get by without a car, as everything is miles away.
A continuously variable transmission (CVT) (also known as a single-speed transmission, stepless transmission, pulley transmission, or, in case of motorcycles, a twist-and-go) is an automatic transmission that can change seamlessly through a continuous range of effective gear ratios.
This is sometimes called a clutchless manual, or automated manual transmission. Many of these transmissions allow the driver to fully delegate gear shifting choice to the control system, which then effectively acts as if it was a regular automatic transmission. They are generally designed using manual transmission internals, and when used in passenger cars, have synchromesh operated helical constant mesh gear sets.
