With regards to the posts above, I have a 2012 Prius plug-in. It has an HUD that was included in the $35,000 package price. The HUD projects at the very lower windshield. It is out of the way but easily visible. It displays speed, power efficiency in a bar graph, and navigation arrows if you have a destination entered (as well as audio commands in a pleasant female voice). It is brighter during the day and softer at night. Works great! I wear "transitions" eye glasses that turn dark when in sunlight and there is no conflict with the HUD. My wife wears polarized clip-ons with her glasses and she can see the HUD fine.
So, in our opinion:
- the HUD in our car is NOT a distraction
- a relatively high tech HUD is possible in a $35K car as standard
- our HUD works great with useful information, it is anything but a gadget
A good HUD, like on a Prius, is essential to us. We hope that it comes standard on the T3, but we will pay extra to get one if necessary.
We also have a primitive AP on our car. It is a radar cruise control that monitors traffic directly ahead only. We have come to depend on it. If the T3 doesn't include this feature, even as an option, that would be a deal breaker for us.
