I am looking for at a new car and have the option of either a conventinal
dash or a digital dash. When I was driving the digital demo, I felt that
I had to read the dash whereas with the conventional dash I could just
look at the dash and gather the info.
I'd appreciate comments from those who have a digital dash. Do you like
it? Would you get another? etc.
Thank y'all in advance.

I agree that the "analog" instruments provide quickly-assimilated information, along with trend info. Digital instruments are fine for accurate details, but do you really care that the oil pressure is 47 psi, or just that it's in the green (normal) range? I also fly my own plane and would have trouble (probably end up dead) if I had to figure out the "trend" on a digital airspeed or altimeter. The needle's motion is instantly apparent, while it would be difficult to determine the direction of change of a bunch of digits. Likewise for engine temps, fuel pressure, etc. The only useful digital readouts for aircraft (in my opinion) are fuel flow, outside air temp, radio tuning, *ground*speed (you don't fly the plane by groundspeed, but you use it to check winds etc.), distance-to-station. The Boeing 767 has analog representations of engine gauges on the video display, along with a digital presentation of the exact number. You can see at a glance what's happening, or home-in on the exact values. Not unlike the "graphic" tach displays in some cars. ============================================================================== Opinions expressed have been generated solely by line-noise. {cbosgd,decwrl,hplabs,ihnp4,seismo}!nsc!cadtec!rick N1150G (408) 942-1535 "The sooner you fall behind, the more time you'll have to catch up!"

Chrysler electronic dashboards only display the speed of the car as digits. The rest of the gauges (including the tack) are "bar graph" type displays. I find that this dash is easier to read than an analog gauges. It's nice to glance down and see that I'm doing 82 MPH (opps, I mean 54). As to sudden changing speeds, I don't need a needle moving around to tell me if I'm speeding up or slowing down. I would, however, like to see along with the "analog" tack a digital tack also. -------------------------------------------- Brian Millham AT & T Information Systems Denver, Co. ...!inhp4!drutx!review How fast was I going? 93.
