Will driving experience benefit flight training? I think my question/situation is a little bit of rare so I start this question and want to hear from you experience pilots.

I'm a 30+ migrant from China working as a software engineer for 10 years. Now I use my weekends taking flight training for Private Pilot Licence in Sydney. Currently I don't see any big problem with my training and probably in next couple of weeks I will have my first Solo. What concerns me is my past experience. I can say I'm rather a good programmer and writing code for computer(iPhone) is really different from driving or flying. My flight instructor tend to say (and I agree) I always fly with the exact numbers rather than make necessary adjustment according to situation outside. So I guess with the past 10 years indoor in-front-of-keyboard office life/experience. The more you get your life/experience aligned with computer/coding, the harder you could get out of it.

What's worse is I don't have any driving experience until two months ago I started to practice for my Australian driver's licence. Now I have my licence issued for one month and I still only drove four or five times with rented car. Though I love public transportation and I'm not that declined to own a car, now I start to thinking about the benefit of driving experience for my flight training. At least driving skills are accumulated with "hours" (which is the same as flying) and it will get me out of computer world.

Do you have any suggestion or advice on this? Thanks for reading and replying. Cheers~

P.S. if possible, my target is CPL one day.
I don't think driver training is beneficial to flight training, the physical acts of driving and flying are too dissimilar. Driving is a handy skill to have for sure, it's usually much easier to get to the airfield for one thing, it's not going to translate to flying though. 

As for flying the numbers you are falling back on what you are good at: attention to technical detail. Attention to technical detail is a very good thing in flying - having a plan and rehearsing for emergencies can save you neck. What your instructor may be telling you is that you need to focus your attention to other details. You may be spending too much time looking at your instruments and not enough looking outside. I did this at first because I had spent a lot of time playing flight simulators and I'm also in IT and spend a lot of time looking at displays in front of my face. The cure is simple: force yourself to get in the good habits of looking outside the aircraft and developing situational awareness. You can only get that through flying practice. 

It sounds like you are concerned that you don't have a sort of instinctual "feel" for flying. Everyone has a different set of aptitudes, some people are better at certain aspects of flying than others. If there's an area you are weak in then focus your training and practice on developing it into a strength.
