No credit? (kidding)

Mine is 120 min/80 min = 1.5

Edit: times are for both ways

I've never really considered my morning prep time to be different. The biggest morning time suck I found was shoe covers and unlocking the bike and getting it out the gate in the fence with a full load of panniers and kid. Also gearing up with my lights and computer after work was the thing I disliked about the winter. I've always hated the extra time needed for shoe covers and lights in the winter; I wished I could just get on it and go.

I find going home is where biking loses as far as prep time goes. I have to change out of my work clothes and get into the bike gear, then reapply gear to the bike. But traffic home is always worse so it is still a win, I tended to pass most co-workers on the line up for the bridge anyway.

In the morning if don't shower at home I then do it at work.

If I drive when I get home I tend to change clothes anyway, so getting back home is no different than the bike.

I never really worried about packing time for clothes. I had a good routine where every about three weeks I'd bring my stash of four or five pants and seven or eight shirts home from work and wash and iron and slowly return them to work for a few more weeks of wear. I would bring undergarments to work and back in a drybag every day. If I took the bus, my likely option when not riding, I tended to change at work anyway so that prep time was similar, just the bus took an hour and twenty minutes on the old route and I never took it on the new route.

I had a spread sheet with costs somewhere but I've not given it much thought in the last nine months. I always kept meticulous records for the car repairs, fuel, mileage, and driving and weather conditions. I always saved all my cycling receipts and started tallying them last winter. Other than brake pads and cables most of my gear lasted multiple years.

In total I am convinced I save time cycling since I'd need to workout and decompress when I got home if I didn't ride.

I just need to convince my wife to let me ride again someday.

I think @wphamilton has a great point. On the old route driving times could be 35-70 minutes for me. Cycling was always 53-56 minutes.

Cycling is reliable time wise was a thing I loved.

Driving is around 22-30 minutes and riding is 40-1h20m depending on how far I go. I am not counting the time it takes to change/ shower/ dress in the morning and change to ride home.
the Mrs appreciates the positives me riding regularly.

I figure the shower is a wash (pun somewhat intended.) I have to shower before work regardless of whether I drive or bike. When I drive I do it before I leave the house, and when I ride I do it after I arrive from work.

Similar to getting dressed. I have to get dressed the first time either way. If I bike, I have to account for time for a clothing change.

True. Where I work I have access to a shower so I don't do that before I leave the house.

This is true. But then again, taking the car to the garage to change oil and filter, swapping winter tires, and other repairs. I just accept the preparation to ride as part of 'the ritual'.

Wow! Yeah, that's huge. Though often my commute involves me riding around for extra miles and I end up doing 2+ hours for the day. My TCQ might end up being 2-3.

Are you driving mainly on the freeway? Or do you have to take a very circuitous route when riding?

Traffic is bad on the commute home by car that is why I try not to drive sometimes I can beat my time home by 5 minutes. Time by car averages between 15- 25 minutes. Time by bike can average between 18 and 22 minutes depending on wind and weather. So to me its almost a wash for time. So I turn to the best thing and that's what I get out of it. Better health, outlook and save enough to by bike stuff. I win!

70 minutes to ride, 30 to 40 minutes to drive; TCQ = 1.75 to 2.3
70 minutes to ride; 45 minutes by bike and train, or 60 minutes by foot and train; TCQ =1.5 to 1.2.

19mi to drive and about the same to ride.
13mi of interstate and 6mi of highway with only 4 lights total.
To ride, it's a lot of start and stop. Probably 14mi of it is on MUPs, but a good bit of those MUPs are in residential, so it's slower going.

I'm a bit envious of that. I have the option of ending my commute to work on a MUP that's only about 2.5-km long, and whenever I get on it it's, phew! such a relief. But I count myself lucky to be able to take several routes that do not require me to stay on any main thoroughfare for an extended period of time. Side roads and residential streets where the speed limit is 50 km/h or less is the way for me.

Driving= 4 miles in 10 minutes
Riding= 6 miles in 25 minutes to work, 20 minutes on the way home.
I take a more meandering route when I bike to avoid busy streets with curbs

Shortest way to work is 5.4 miles.

Driving to work takes 10 minutes.

Cycling to work takes 25 minutes.

I don't know what the ratio is.

I hate math.

It takes me 20 minutes door to door whether I ride or drive so my number is 1.

There are more stoplights on the driven commute than the bike commute. It's typically 20-25 minutes driving and 25-31 minutes biking for a ratio of 1.25. When I drive, I average 16-18 mph or so; bike is 13-15 mph.

Don't have exact numbers but; This morning it took ~30 min to get to work. The drive would take ~25 min. That yields ~1.2.

My typical ride home is ~25 min. The drive is from 20-25 min. That yields from 1-1.25 depending on traffic.

Yesterday I went the long way home. ~55 min. If I went for a joy ride in my car after work it would be for at least 2 hrs more like 3. Using the 3hrs, rounding 55min to 1 hr that yields 1/3!

Ouch, over engineered. I'm coming from my artist side. In the car, grumpy like all the other cagers, on the bike, happy like all the other bikers. So it's the HGQ. How do you like to spend your commuting time?

1 for me - bike, car, or bus/subway (all about a half-hour).

I haven't driven, but judging by the number of cars I pass on a 30 - 35 minute ride on the way to work, the bike would be slightly faster due to traffic. Maybe I could make it home 10 minutes faster by car on the way home (again depends on traffic).

Biking + train + walk to work is around 35-45 minutes. Walk + train + walk is the worst as like 50-60 minutes.

Commute is less than 8 miles. 17 to 18 minutes by car, or ~35 minutes or so by bike, depending on how hard I want to ride and whether there is an afternoon headwind from the northwest.

My quotient is about a 2.0, I guess.

My commute takes 89mins on average as a round trip, vs. 60 in the car - there's lots of congestion on the route home. So that gives me 1.48

My car commute is much shorter than my bike commute. So, it's not even close. Round trip: 1 hr by car versus 3 hours by bike. But---it's really about getting three hours of exercise several days a week anyway.

My TCQ is 2,3333....
It takes me ~30min to drive to work, while it takes me 1:10h to ride to work (15 kms commute, each way)

Mine is 1.59 on a good day and doesn't vary from that too much. I take a slightly longer route on the bike for safer roads on my 12 mile (each way) ride. Only 2 traffic signals coming in and 3 on my return and one busy road to merge into for a left hand turn.

My average speed is about 20.5 mph on the bike.

I use my commute for training so usually I'm pushing pretty hard.

I have limited time to bike so taking advantage of the time I would otherwise be driving has been a real bonus.
