Improve your car with the new bicycle-bell-inspired “secondary car horn” option. Now you’ll have options besides just honking at people! Unless you are a goose, in which case that will remain your only option.

The issue:

Imagine that you are driving a car down a narrow road and you see a person unloading groceries from a car trunk.

There are two common options:

  1. Continue driving: hope the person unloading the car doesn’t walk out into the street
  2. Honk the horn, to inform the person unloading the car that you are there

The second one is safer, but is considered extremely rude.

Thus, in real-world scenarios, most people will probably politely run over the car-unloading pedestrian rather than honk potentially unnecessarily.

The root problem here is that there is no “polite” way for a driver inform others of their presence. This is also becoming more of a problem as quieter electric cars become more common (so the car engine isn’t generating a “hey nearby people, a car is running” sound at all times).

Proposal:

This was solved ages ago for bicycles with the traditional bicycle bell, which conveys the sentiment “in case you weren’t aware, a bike is passing by!”

The car horn, on the hand, conveys the accusative sentiment “hey, you have committed some major driving error!”

What is needed is the bike-bell equivalent for a car—a “more polite” horn (Figure 1).

Fig. 1: Left: a traditional steering wheel only features a startling “honk extremely loudly” option. Right: we can add a bicycle-bell-inspired “chime to inform pedestrians of a car nearby” button as an alternative to the normal car horn.

Conclusion:

Why isn’t this a feature, anyway? It seems like this should have been standard on cars since the mid-1980s.

PROS: Improves public safety and may reduce the number of people run over every year.

CONS: Adds one cent to the manufacturing cost of the steering wheel.
