This is obviously a very personal preference. I never had one in previous vehicles and now that I do, I really like having it. I believe it adds an element of safety to driving and I rarely ever look away from the road at my speedometer anymore. If you understand its purpose and use it correctly, it is not a waste of time and is one more tool available to the driver. This isn't an entertainment device for others in the car and its not there to add excitement to your drive.

Like I say, maybe I'm missing something. .... Please explain how does one use the HUD correctly (versus incorrectly)? I'm not suggesting the HUD, unto itself is a waste of time ,but trying to retrofit a vehicle to include a HUD might be a waste of time and money. And I agree, it'* a personal preference. If a person thinks the time and money to perform such a retrofit is worth it.......... then it'* worth it!

the idea behund the HUD is to show the driver the spped of the vehicle with out looking away from the road. this keeps the focus on the road instead of glancing down and the speedo from time to time....i can remember the last time i actually looked at the speedo on my cars.......and i actually feel weird when i drive cars with out HUD now

As Pat mentioned, the idea is to maintain focus on the road. By adjusting the display to be low in your field of vision and incorporating it into your scan, the information is apparent but the driver can continue to watch what'* going on around them. This decreases the dependance to catch something in peripheral vision while looking down. Not only with speed, but while using the stereo. Generally, the vehicles equipped with HUD also have steering wheel controls (these are relatively easily added to the Bonneville, even if not equipped). This allows the driver to use these controls while the station or disc/track number are displayed without looking down at the radio. Again, if adjusted correctly allows the driver to continue looking forward. A warning message, high beam indicator and signal lights are also displayed to complete available information. Collisions happen very quickly and with people foolishly texting messages, eating, sorting through CD'* or a number of other distracting activites, I prefer to maintain forward vision with as little interruption as possible. Earlier detection of others actions = increased reaction times.
