An honest, source-cited breakdown of what it really costs to get around San Diego — including the times when driving yourself or taking a rideshare is the better call.
Questions? Call (858) 522-0264No single option always wins. Short, off-peak, solo trips: rideshare or your own car is usually cheapest — and we'll say so. Multi-day airport trips, groups, long-distance routes, and big events: a flat-rate private car is often the better value once parking, surge, fuel, and the true cost of driving are counted. Below is the real data, with sources, so you can decide.
A drive in your own car feels free, but it isn't. AAA's 2025 study puts the all-in cost to own and operate a new vehicle at about 28.9 cents per mile — roughly $11,577 a year at 15,000 miles (AAA, 2025). The IRS 2026 business mileage rate is 72.5 cents per mile (IRS, 2026), which reflects fuel plus wear, depreciation, and maintenance.
For a short local errand or a 1–2 day trip where you'd park economy, the marginal cost of your own car is low and self-driving usually wins on raw dollars. If that's your trip, do it yourself — we'd rather tell you the truth than sell you a ride you don't need.
Per the San Diego County Regional Airport Authority (verified April 2026):
| SAN parking option | Rate | 3-day trip | 7-day trip |
|---|---|---|---|
| Economy lot | $20/day | $60 | $140 |
| Terminal garage | up to $32/day | $96 | $224 |
| Valet | $40/day | $120 | $280 |
Add fuel and the round-trip drive each way. The longer the trip, the more a flat-rate round trip competes with — and then beats — parking plus gas. See the worked example for Alpine → SAN.
Uber and Lyft are genuinely the cheapest, most convenient option for many short, off-peak, single-rider trips — no question. Where they get expensive or unreliable is the predictable stuff: surge pricing during peak demand, after big events, and in airport/late-night windows; longer waits at crowded pickup zones; and variable pricing you can't lock in advance. A flat-rate private booking trades the cheapest-possible fare for a price locked at booking, a known vehicle and driver, and no surge — which matters most exactly when rideshare is at its worst (events, groups, long hauls, early flights).
One person, a short city hop, no event letting out, no surge on the app right now? Take the rideshare. We'll be here for the trips where locking the price and the vehicle is worth it.
And there's a factor only one option offers in San Diego: EGT is 100% electric, so every one of these trips is zero tailpipe emissions (US EPA; US Dept. of Energy). Flat-rate, TCP-licensed (#0046494-A), $1.5M insured.
If self-driving or rideshare is genuinely the better call for your trip, we'll say so. If a flat-rate electric car wins, we'll show you the math.
