I pit Honda for not having a locking fuel door or fuel cap on the Insight.

On my last car (a Smart) and current car (a BMW) the fuel door is locked when the car is locked and unlocked when the car is unlocked. No remote releases needed, simple and elegant.

My '96 Contour has a locking gas door with a release on the floor next to the driver’s seat.

Funny you mention that model; that was the same as mine, with the gas latch that failed.

That would annoy the crap out of me for the first few tanks of gas. As soon as I get out of my car and close the door I reflexively hit the lock button on my fob. I regularly get out of my car and by the time I get to the hatchback to unload whatever I bought I’ve already locked it.
