Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / December 2007digital speed
I was just wondering why most cars don't have a digital readout of your current speed as opposed to the gauge. I think a readout would be easier for the brain to process, possibly reducing accidents.

Well, he says "digital readout", so I guess I must be going out on a limb when I equate "readout" with "instrument" or "gauge".

Maybe he's playing semantics with whether the underlying information is digital or not. But what the driver SEES is analog if the gauge has a dial and pointer (or bar graph in the case of a '62 Oldsmobile). Just like you don't hear digital sound out of your MP3 player speakers. And for what its worth, digital information is conveyed by analog voltages that are interpereted as digital bits (with the occasional error that has to be corrected). > > I think what marsh is saying is if it don't have a cable, it aint analog. > [quoted text clipped - 6 lines] > voltages that are interpereted as digital bits (with the occasional > error that has to be corrected).

What reduces accidents is carefully heeding the dynamic requirements imposed by your surroundings and the car's behavior. Speed itself has little or nothing to do with it. If you're relying on a number on a readout to decide if you're driving safely or not, you're either a politician or a very new driver. SignatureTegger >I was just wondering why most cars don't have a digital readout of >your >current speed as opposed to the gauge. I think a readout would be >easier for the brain to process, possibly reducing accidents. It's not. It's actually much harder. Some car manufacturers tried this in the seventies and it was very difficult for drivers to deal with.

I was several weeks, if not months before I really got used to it in my 95 Caprice but once used to it it was as good or better then any other speedometer I've relied on. For some things its far better. Some of the work I did required very tight control of speed and monitoring it with the digital was easier then with a needle gauge. > I was just wondering why most cars don't have a digital readout of > your > > current speed as opposed to the gauge.

Having to 'read' something VS just glancing over to see that the line is still in the top center (where most sit for highway speed) would be a lot slower in my mind.

Agreed. Same reason digital watches didn't take over the market- its quicker to look at an analog watch. Also the same reason that even "glass cockpit" airplanes have many indicators on the flat panel screens that mimic analog gauges. Seeing that "all the needles are in the right zone" is much quicker than reading the exact inlet turbine temperature on all 4 engines and then mentally asking yourself if each is correct, reading the exact oil pressure, reading the exact propeller RPM, etc. In a quick scan, it would be easy enough to confuse "6800" with "8600", but it would be immediately obvious with analog gauges. >>> I was just wondering why most cars don't have a digital readout of >>> your [quoted text clipped - 18 lines] > would be easy enough to confuse "6800" with "8600", but it would be > immediately obvious with analog gauges. Wife's car is a Beretta with a digital dash. My cars aren't. I _prefer_ regular gauges, but on the highway, it's nice to see your speed in big numbers. The tach is useless and the aux gauges are just bar graphs, so they're like mini analog gauges. My $.02 - I think digital gauges would actually work fine if the mfr's made them useful instead of sexy. They would work fine for "static" type gauges such as speedo and volts, but they don't seem to work as good for rapidly changing ones like a tach. For example, your voltmeter moves from say 13.8 to 13.9 and back again while driving, but if you're racing and watching the tach, if you can make out the digits on a readout, your car is too slow. It's mostly marketing why cars don't come with proper gauges in the first place. I look at 70's cars and laugh - the square speedo, a fuel gauge, and a row of idiot lights...

Very poor idea as a replacement for an analog gauge with pointer. >On Dec 11, 11:12 pm, b...@coolgroups.com wrote: >> I was just wondering why most cars don't have a digital readout of [quoted text clipped - 7 lines] >impossible to note rate of change. Very poor idea as a replacement >for an analog gauge with pointer. I note my rate of change by the acceleration my body feels, not be looking at my speedometer needle. I can only speak for myself, but once I got used to my Digital gauge it could read it just as quickly and easily as the old style analog. The poster that mentioned tachometers made a good comparison... For speed, a well designed digital can be as good or better then analog due to the purpose you use the gauge for. But for engine RPM for max performance, an analog makes more sense, you really don't care what the "number" is, you just need to know when you are "there". Which is why some people also use a light that turns on when a predetermined rpm is reached... while driving they don't care what the "number" is, they just need to know they are at the shift point.

Speed limit signs are written as numeric values, not as pie charts. It would appear static values are well suited to being written as numeric, while rapidly changing values or where you only need a range of numbers, do better as an analog gauge. A digital tach is useless for acceleration and racing purposes, but it's nice (although not really useful) to know exactly what rpm you're turning once up to speed in a regular passenger car. Ray |
