I wonder how accurately the trip computer calculates Miles Remaining?
 
Based on my measurements, it's 4%-5% optimistic.

I don't buy the argument that the guages aren't accurate.
They are very close to what its supposed to be, that's why they are there.
The temp guage is right in front of you next to your mph guage. There is no excuse for not paying attention unless you don't look at your guages at all. I drive manual so I look at the guages panel all the time.

 
The temp gauge isn't accurate. It's designed to indicate half way between hot and cold unless the engine is really hot or really cold. Think about it, have you ever seen the needle move even a millimeter once the engine has reached operating temperature? In contrast, the coolant temperature gauge needles in my 1975 BMW 2002 and 1999 Wrangler move around quite a bit.

I suppose what this discussion shows is that the degree of accuracy is based on a driver's perception. For many drivers, a simple indication that the engine is within the acceptable range or not, is likely enough. And, if one uses common sense one can avoid problems. Now, on a hot day with a loaded car moving slowly up a hill, most drivers would like know that the guage is working in case there is a problem. Reminds me of one hot summer's day in New York City when my co-driver learned the lesson the hard way; we ended up stopping the car a few times to give it a chance to cool down.

I guess it's OK for a commuter car or grocery getter, but when I'm on the track I want to know exactly what the coolant temperature is doing. The last thing I need is for the gauge to suddenly indicate full hot just as the coolant starts to boil over- all while I'm trying to slow down from 130 mph to 80 mph for Turn One at Putnam Park.

Precisely. I think you would agree most drivers being commuters would not run into this scenario, and, it would be safe to say, you're not the average grocery getter.
 
Personally, I'm waiting for the technology that slaps sense into drivers trying to manouevre through inner city traffic, construction sites, highways exits/entrances and the like while texting on a cellphone. This increases my temperature.

I agree with you 100% sonnyrocker. Case in point. the temp gauge on my '97 Civic finally went above the water line and started approaching the redline. I've had the car since day 1 and this is the first time it's ever happened (and I do keep an eye on my gauges). It happened a half mile after leaving the house (was still warm from a previous trip) and I was able to pull off and slow down, before a major overheating, and make it back to my condo w/out cracking a head. Turns out the upper radiator hose and heater hose cracked and began leaking fluid. That gauge cost me $250 in repairs vs. thousands for a new engine.
 
I just don't understand how Mazda overlooked this! It's just seems so fundamental to me to include in an instrument display.

The 2010 mazda3 is a overall well done car, but the mpg needs to be there if mazda wants to compete with the cars that get 35 to 39 mpgs, that includes the both the i and s models. They should give you a choice on what size rim you want on the car. My overall mpg on the mazda3 sport is as low as 25 and as high is 30.The only thing i don't like is the 17' rims. If anyone needs tires for the 3 try Tirerack.com they have the tires for alot less than if you went to a tire store.

Considering that the Mazda3 is Mazda's best seller, and is considered one of the best cars in its class for 7 model years now, I really do not think that statement is true. Besides, what car in this class gets 39mpg? I can't think of one. Not even sub-compacts like the Fit or Yaris or Accent get that.

An opinion is neither "true" nor "false."
 
Several cars in this class can get 35 to 39 mpg on the highway: Civic, Corolla, Elantra, Focus for example can all reach upper 30s on the highway. Actually the Mazda3i can also, at least the pre-2010 cars could. And there are some mid-sized cars with power comparable or better than that of the Mazda3s that can get over 35 mpg on the highway. I am talking about real-world mpg vs. EPA here. If the original opinion was regarding average fuel economy or EPA numbers, then I agree that is a stretch for a car like the Mazda3 since there are few cars of any kind that hit those numbers.

The 2.0L MZ3 'i' with 5-speed manual has an EPA highway rating of 33mpg. The highway rating drops to 29mpg for the 2.5L in the 's' models. For the sake of comparison, the Civic Si is also rated at 29mpg and the Toyota Matrix (2.4) gets 28mpg highway.
 
The Civic (1.8L) has an EPA highway estimate of 34mpg (manual) or 36mpg (automatic). Ford Focus, using the same 2.0L engine as the Mazda3 i (w/o VVT), gets 35mpg highway. So there's no question, that there are other small cars with better fuel economy than the Mazda3. But most (all, IMO) aren't nearly as much fun as to drive as the MZ3. Quite a few buyers (based on sales figures) are willing to sacrifice a few mpg to get the "Zoom Zoom"!
 
In most other markets (including Canada), Mazda offers the 2.0L engine in both the 4-door and 5-door bodystyles. The U.S.-spec 5-door is unusual having the 2.5L engine and 17" alloy wheels standard. In Canada, you can get a 5-door with 2.0L and 16" steel wheels. I'm surprised, especially considering current economic conditions, that Mazda didn't offer the entry-level 5-door model here in the U.S.
