Attaches to windscreen via suction

How’s this for a cycle lane parking deterrent? A great big limpet that obscures the driver’s view.

Wheel clamping is costly, awkward and time-consuming, but ETA reports on an alternative. Secured with suction via an in-built pump, the Barnacle is said to be almost impossible to remove.

The lightweight device is easy to apply and also boasts an anti-tamper alarm. If you find one on your windscreen, you simply pay your fine over the phone after which you will be given a code to remove it. You then have 24 hours to return it to a drop-off location to avoid another fine.

The manufacturers claim the Barnacle makes parking enforcement easier for all parties involved: administrators, enforcement personnel and the offending driver. They’re currently priced at $499 (around £385).
