True, they're not the most brilliant cameras in the world. When I'm racing I use a lightweight full-HD camera too, and you can tell the difference, especially in the price tag. It's cheap, what more do you want? Yes, you can read license plates if the capture is in daylight. They do have problems with vibration, and with some SD cards. I've found the recommended SD card has more problems than a generic 133x card. Don't ever let it fill the card, i.e. stop it at 1 hour. The software can't handle reaching the end of the card and has ruined more than one card before I worked out what was going wrong. I've found that Li-Ion batteries will last all day, but remember you have to change cards every hour. It doesn't handle cold too well.
