How about do and end run:
Have him learn to steer BEFORE giving him something with a motor to steer?
PlasmaCar this year (although be warned... our neighborhood started these at 2yo and all the kids are STILL riding them at age 9 - 11) and PowerWheels NEXT year. ((aka put off having to do an absolute ban... "This would be GREAT, when he's OLDER... brilliant idea honey, but lets wait a year and get his motor skills and listening skills improved, etc.")

Note... they're more than sturdy enough for adult weight (although they're not as agile with adult weight on them) and we started requiring helmets at age 3 when the kids started going down hills. The neighborhood kids STILL (going on 10 years later) tend to prefer these over bikes. If you have tile in your house, replace the wheels with rollerblade wheels (your bike shop will do it) to save on you hearing/sanity as the stock wheels are loud.
It's a "big" gift. Sturdy, safe, SUPER fun, indoor and/or out... and is *perfect* for a 2yo. My newest niece I'm just chomping at the bit (she's 1) to get old enough for her own.
BEST riding toy EVER.
Huzzah for "The Scoocher!" (the motion the kids make with their legs to push them along. You can just use the butterfly shaped -not girly, but not round' handle bars to propel yourself, but it's not as fun as using your feet to push and glide)
