SMIDSY principle: Bikes seem out of nowhere

A brand new principle about what causes Sorry Mate I Didn’t See You (or SMIDSY) crashes is that bikes can seem out of nowhere like planes and ships.

Rider security exert Kevin Williams of British rider coaching firm Survival Skills calls the phenomenon the “constant bearing, decreasing range” subject.

I’ve reported for a number of years on varied theories that may result in SMIDSY crashes.

You can take a look at a number of the scientific research into SMIDSY by clicking right here.

The causes will be something from drivers not bothering to look, seeing us however not caring due to the diminished risk, not seeing us due to “saccadic masking” (see video under), and plain stupidity.

One of the ideas we make is to weave round in your lane to draw the eye of different motorists.

Kevin agrees that that is necessary as a result of a static rider is a small goal that’s troublesome to see and whose pace is troublesome to guage.

He says it’s like an approaching airplane or ship on a relentless bearing.

“The problem is that lack of lateral movement to attract our attention, and there’s a very specific form of motion camouflage that happens when two moving vehicles are on a collision course,” he says. 

He says the issue is called the ‘Constant Bearing, Decreasing Range’ subject which is a time period utilized in navigation and flying.

It implies that some object, often one other ship considered from the deck or bridge of 1’s personal ship or one other plane considered from the cockpit, is getting nearer however staying on the similar angle – or sustaining the identical absolute bearing.

“If they both continue on the same course at the same speed, they WILL collide. And it CAN happen on the roads,” he says. 

“Just ask your self the place; for instance, while you’re approaching a roundabout and one other car is on an intersecting course and can arrive on the similar time, or when approaching a cross-roads and one other car is approaching head-on. 

“Since neither vehicle will appear to move relative to the background, it can be difficult for either driver/rider to perceive the other, even when in clear view.”

He says riders can not depend on drivers predicting that there is likely to be a motorcycle they will’t see, so it’s as much as riders to draw the motorist’s consideration by breaking the Constant Bearing drawback.

“All we need to do is change position and speed and thus create some lateral movement,” he says.

“Hopefully the driver will now see us though a wise rider would still be prepared to take evasive action,” he says.

Riders must also establish something which will block them from a motorist’s imaginative and prescient and transfer out from behind it to allow them to be seen;.

“That way we ‘uncloak’ our bike, and at least give the driver a chance of seeing us.”

It nonetheless doesn’t imply they gained’t understand a motorcycle as a risk nor that they may misjudge our pace, so take care on the market.
