We used straight TTL for the robot this year, and we covered at least 5 feet without any communication trouble, plus the connection was a lot steadier and less prone to wiggling free than with the driver chip. Plus that little (breakable) chip being a failure point for our targeting functions made us nervous.

I'm a FIRST relic of sorts, I remember when we used PBASIC and we got CH Flightsticks in the KoP. In my day we didn't have motorized carts, we pushed our robots uphill, both ways! (Houston 2003!)
