I don't get how using lyft/uber as your only form of transportation can be at all cheaper.
Let me run some basic math. Uber wants $11.50 to take me home right now. Lyft wants $13.40
$11.50 * 2 = $23/day
23 * 5 = $115/week
$115 * 52 weeks = $5980/year (I am ignoring vacation weeks for now.)
My yearly cost for car ownership are roughly as follows. (Assuming only work and back.)
Insurance(1): $886/year
Fuel(2): $292.50
Maintenance(3): $1000
Car purchase price(4): $1000
Total yearly cost: $3178
(1) I only run Liablilty + uninsured/underinsured but I run cheap cars
(2) 2340 miles/year (Work is just under 4.5 miles.) Figure 20 mpg (I get better but have not calculated it in a while.) Figuring fuel prices at $2.50 although the last year has been much closer to $2 and less at times
(3) This is way more than I would put into a car yearly if I only drove it to work and back but I do many of my own repairs so I am boosting it a bit for those unwilling to do so. Also including stuff like taxes and tags here
(4)I buy cheap cars off craigslist, run them into the ground and replace them. My normal cost is $500-600 but by the time you add a new set of tires ($250-300 installed) and fix whatever random issues the car came with $1000 is closer to actual purchase price.
