a sense of continuous acceleration albeit with less precision: a gauge reading could only be estimated to the pointer's nearest halfway point between the markings. The first digital instrument clusters were considered to be unpopular during the years when they were widely produced, and were heavily criticized by reviewers in automotive magazines. Some of the criticism they received was as follows: They were hard to see in the strong sunlight or other bright light They took away the sense of continuous acceleration that is provided by an analog speedometer. They were expensive to repair in the event of a malfunction As a result of these issues, digital instrument panels were phased out of vehicles throughout the 1990s, and have been replaced with traditional analog gauges in most vehicles (with notable exceptions from French manufacturers Renault and Citroën), including those from luxury divisions. However, many vehicles are made today with a standard or optional trip computer located independently from the speedometer. Digital units received information from a variety of sensors installed throughout the engine and transmission, while traditional analog units were attached to a cable that provided information from the transmission. Modern analog displays receive information in the same manner as the digital units, with very few manufacturers still using the speedometer cable method. In the 2000s, digital speedometers were produced in some hybrid vehicles, including the Toyota Prius and Honda Insight. Most digital speedometers have had green numbers displayed on a dark green or black background. The 8th and 9th generation Honda Civic have a "two-tier" instrument panel. The upper digital dashboard with white numbers against a blue screen (the latter of which changes to green according to driving habits), digital fuel and temperature gauges. The lower dashboard has an analog tachometer and digital odometer. The 10th and present generation saw the two-tier design replaced with a single instrument panel, which in higher tiers is a fully digital and partially customizable design. Since the mid-2010s and early 2020s, fully customizable digital instrument clusters have become popular. The modern implementation allows the driver to choose which information to project where and how in the instrument cluster, such as navigation aid, connected phone information and blind spot camera view. The customization can also reduce distraction for the driver and allow the manufacturer to use the same hardware in different models while retaining differentiation between models.
