I was driving 85 miles to work one way (170 miles round trip per day) four days a week for five months
cause I accepted a job that paid VERY well , but I was undecided if I really wanted to move to that area. Luckily I was driving a company car.
Since then I have transfered much closer to my home. But well paying jobs are so tuff to find now or days that I had no choice but to drive almost 700 miles per week until I could transfer and be bicycle riding distance to work.
Yes, its very wise to find a job close to home to cut down on gas usage, tolls, wear and tear..... not to mention the more you drive, the greater risk you are being in a car accident.
