Car Ownership vs Taxi Hailing App - What makes financial sense?

Yesterday, I used the Olacabs app to book a autorickshaw to go to Bangalore's Wholesale market - K R Market and back to home. Total cost was Rs 75+ Rs 55 = Rs 130

If I had driven, I would have burned atleast 2 liters of petrol that would have cost me close to Rs130 + parking of Rs 30 or so totaling to around Rs 160. Worry, stress and struggle to find parking are free.

I just did a quick math to see if it made financial sense to sell my car and purely depend on taxi hailing apps for my family's commute.

My daily home office home run is around 30kms. Weekend travel is very limited and is usually around 20kms over the weekend.

Some assumptions I made for the analysis
1. The car owned is a mass produced petrol hatchback/entry sedan with a fuel efficiency of 12 kms/liter
2. Took the most expensive cab category - sedan. mini and auto are a bit cheaper. Not considered the peak hrs rate
3.  I would rent out my apartment parking space :)
4. Took the most expensive insurance which would be atleast Rs 1000/month for a 2 yrs old car
5. Assumed a maintenance cost of Rs 4000/year
6. Other expenses like -car wash etc add to Rs 1000 per month
7. User buys a new car every 4 to 5 years

This is how it looks

Car Ownership cost/month

Category	Cost
EMI/Month	INR        15,000
fuel	INR          5,250
Insurace/Month	INR          1,000
Maintenance	INR             333
Others	INR          1,000
Total/Month	INR        22,583

This is the typical Taxi costs across different categories today in Bangalore

Type		kms	rate	Rate/km
Mini	Slab 1	4	80	20
	Slab 2	1	10	10
Sedan	Slab 1	4	100	25
	Slab 2	1	13	13
Auto	Slab 1	2	25	12.5
	Slab 2	1	10	10

This is what it would cost by using a taxi hailing app

Taxi Type	Sedan
Home-Office-Home
One way Distance in Kms	15
Slab 1 Cost in INR	INR           100
Slab 2 Cost in INR	INR           143
Cost/trip in INR	INR           243
No of office days	20
Total Cost/month in INR	INR       9,720
Other Commutes
kms	10
Slab 1 Cost in INR	INR           100
Slab 2 Cost in INR	INR             78
Cost/trip in INR	INR           178
No commute days	20
Total Cost/month in INR	INR       7,120
Total Cab Cost/Month	INR     16,840

So the monthly savings

Savings by using Taxi hailing	INR          5,743
Rent from my parking in Apt	INR          1,000
total savings	INR          6,743

Of course, there are costs that will reduce every year like insurance and costs that would increase like Taxi cost etc 

After a 4 to 5 years there is no EMI

What my calculations says is that if you have not purchased a car yet you do not have to if your commute is similar to the case study above.
