For every problem there is a solution and a heads-up display solves automotive problems like the steering wheel blocking the dashboard display or the speedometer goings off calibration.
A heads-up display also solves the problem of losing focus on the road when looking down too long at the dashboard display. 
While not all cars come with a heads-up display built-in, you can get an aftermarket heads-up display like the Hudway Cast heads-up display that is easy to use, easy fit and can help you keep focus on the road without lowering your eyes, which is the main purpose of a heads-up display.
Hudway Cast is designed to be used via the apps on your a smartphone or tablet to eliminate the need of using a dedicated satellite navigation system in your car.
Hudway Cast essentially projects a virtual display of your car's instrument-panel display via a small TFT display located behind the lens panel of the Hudway Cast.
When powered on, the TFT display reads "Waiting for iOS device or Waiting for Android device", as well as the Hudway device name.
To toggle between Android or iOS connection, you press the button with the circle arrows. The + and - buttons control the brightness of the display.
Hudway Cast works similarly to the Glass heads-up display version but instead of reflecting the information from the smartphone screen directly into the lens panel, the Hudway Cast uses a very bright TFT display to cast information from the smartphone screen into the transparent lens panel.
The Hudway Cast has a clamshell cradle design but you don't place the smartphone on the clamshell cradle. Instead, you mount it above the air vent via the included magnetic car phone holder.
Utilizing a magnetic phone holder with the Hudway Cast is definitely an improvement as it keeps your smartphone securely mounted without having to worry about your phone flying off the clamshell cradle.
