In your situation it all depends on how your passing and at what rate you’re passing mr. truck. Assuming you’re passing on the left, are you passing in a way that you just stay on the right part of the lane or are you passing in a way that immediately puts you to the left of the lane. That extra space between you and the offending vehicle gives you the extra time to increase your options… brake, accellerate more, keep your delta, honk, flip off driver, etc… Is your delta just barely passing? ie. vehicle going 60mph, you passing at 65mph… then you’re passing wrong. In your situation if you’re just about done passing offending vehicle, why would there be a danger of him drifting or mergine into your lane? You should already be at a delta to be safely pass the vehicle and out of the vehicle’s blind spot, ie. there’s no way the driver shouldn’t see you. I’ve personally, never had that happen to me. I’ve had vehicles merge/drift into my lane when i was directly adjecent to the vehicle, but never when the nose of my bike was just slightly passed their vehicle. If the drifting starts when youre adjacent or in the vehicle’s blind spot, i’d say it’s a personal choice on whether to brake or accellerate (i’d highly suggest always using the horn though). But by saying you’re just about done passing means you’re basically passed the vehicle at a faster delta rate already. Not saying your situation couldn’t happen, it just seems unlikely… the driver would have to be completely stupider than the average driver (possible), the driver would have to be having a really bad day and just itching to run you over (slightly possible), or the DMV is giving licenses to legally blind folk (unlikely). Either way, I would contend that any time accelerating is your only option just means you’ve done a lot of stuff wrong beforehand already regarding S.E.E…
