At face value, just commute time savings is HUGE and easily calculable. I also spent a significant amount of time figuring out what to wear, ironing, accounting for weather, packing my bag. It was 40 mins of "commute" but also like 40 mins of "getting ready". I'm saving 1:20 per day now which is almost a whole day per week.
Yes. Not to mention the hidden time cost of owning a fully functioning car. Light broke, or it won't start? I have to fix it in my own spare time, bring it to the mechanic and so on.
