The advantages of motorcycling - including more predictable journey times and lower fuel consumption - have encouraged a recent revival in biking, especially in urban areas.
But commuters on two wheels have to cope with a host of hazards - not least car drivers who for various reasons fail to see motorcycles and scooters.
Too often car drivers look but don't see motorcycles. This problem is especially bad at junctions, which is why it is the subject of a UK advertising campaign - but the message is equally valid in South Africa.
"Sorry mate I didn't see you" is for too many bikers the last thing they hear before they are put in an ambulance.
So, don't forget to check carefully for small, fast-moving vehicles before you pull out; as the old slogan says: "Think once, think twice... think bike".
Keep checking your mirrors for bikes if you're stuck in heavy traffic; SA road law requires motorcycles to have their headlight on at all times which makes them easier to see.
If the rider is "lane-splitting" - riding between the rows of stationary or slow-moving traffic, make a bit more space for him (or her!) if you can do so safely.
By pulling over slightly you can make the difference between letting the bike past or adding one more vehicle to the gridlock. Just remember to check your mirrors first: you don't want to knock down a cyclist on your left making way for a biker on your right.
Don't express your frustration with slow traffic by deliberately blocking a motorcycle; you won't go any faster and if you cause a collision you'll be r really late getting to work.
But that cuts both ways: if you're the biker, don't be aggressive when working your way through the traffic.
A smile and friendly wave will get you safely past a lot more cars than any amount of flashing headlights and engine-revving. The car driver you annoy today won't be keen to give you a gap tomorrow.
