I always draft big rigs on the beltway. Being in the middle of the lane, I have had zero issues with debris hitting me in my open face helmet. I'm probably 2 bike lengths behind. Just enough that I'm in the low pressure area and I can't feel the wind buffeting my shoulders/arms anymore.

Been a biker since the late 90s and I'll keep doing it.

What happens if there is large road debris (such as a shed tyre)? You have something like 1/10th second to avoid it at that distance & speed which is too fast for human reflexes.

The moment I worry about every little think that might happen on the road is the moment I sell my bike.

Also, you've obviously never been on the Capital beltway or you'd never ask that

99% of my "highway" driving is on the local interstates in the DC area. I have a greater chance of getting killed by a dear (3 close calls to date) than road debris (no incidents). At night, the beltway can be a ghost town. At daylight hours, you can be lucky to get to 65 non-rush and 35 if you're lucky during rush. One little incident can have a ripple effect and it can become a parking lot REALLY quick.

We have a thing here called "rubber neck delays" because of something that happens on one side of the interstate that causes people on the other to slow down to 25-30 so they can look, instead of driving like they should.

I would love to see how Jeremy Clarkson would handle our beltway at rush hour. He would lose his mind, lol.

Back on topic, the reason I draft is you have three choices: Back far off behind the rig so the wind doesn't whip your bike around, pass them if you have that option, or speed up and get in that "pocket". I always choose option 3.

Average driving speed in the centre of London is around 10-12 miles per hour... :-) Clarkson/Hammond/Stig/Capn Slow did a top gear race where they tried different methods of transport through the city. If I recall correctly Hammond won using his bicycle (Clarkson was on a motorboat, Stig was on public transport, James was driving a Merc).

Clarkson also did a London race against a marathon runner, the guy on foot got to the destination first, beating clarkson in his car.
