Ride Los Angeles → San Diego with a driver already making the trip. Split the gas instead of paying a markup — no surge, no airport, no markup.
All the realistic ways to make this trip — including the ones that aren't us. Prices checked July 2026; where we haven't verified a fare ourselves, we say so instead of guessing.
| Option | Typical cost | Time | Notes |
|---|---|---|---|
| Seat Sherpa carpool that's us | $15–$28 | 2–2.5 hours | Door to door. Split the driver's fuel — no surge. |
| Drive it yourself | ~$19 of gas | 2–2.5 hours | 120 mi ÷ 30 mpg × $4.80/gal. Before parking, tolls and wear. |
| Bus (Greyhound / FlixBus) | Varies | Slower — usually 1–2 h longer | Fares move constantly; we don't quote numbers we haven't checked today. Check fares → |
| Train (Amtrak) | Varies | Slower; often a bus connection | Not all California city pairs have a direct train. Check fares → |
| Fly | Varies | Short in the air, ~3 h of airport either side | Can win on long corridors if booked early; rarely on short ones once you add transfers. Check fares → |
Seat Sherpa prices are live seat prices from our own marketplace. Rideshare figures are real screenshotted quotes with the route and date shown — never extrapolated. Bus, train and air fares change daily, so we link to the operator rather than publish a number we can't stand behind.
Downtown LA, Westwood/UCLA, Santa Monica, Pasadena and the Valley.
Downtown, La Jolla/UCSD, Pacific Beach and North County.
Seat prices usually run $15–$28 per seat. You're splitting the driver's real fuel and wear cost — capped at the IRS mileage rate — so there's no surge pricing and no markup.
About 2–2.5 hours, covering roughly 120 miles depending on traffic and stops.
A carpool seat is usually the cheapest door-to-door option at $15–$28. Driving yourself costs about $19 in fuel alone (120 miles at 30 mpg and $4.80/gallon, before parking and wear), and that's before you split it with anyone. Bus and train fares change daily and are usually slower; flying can win on cost if you book early, but rarely once you add three hours of airport at either end. Prices checked July 2026.
For most trips, yes on the all-in cost. At $15–$28 you split fuel instead of paying for a full tank (~$19 for this route), you skip airport time, bag fees and transit transfers, and you get dropped closer to where you're actually going.
Yes. Add a note when you book (for example "1 suitcase" or "a snowboard") so the driver can plan trunk space.
