The Pit-Bul from Pacific Scientific is an alternative to often dangerous spike strips. This "portable non-lethal vehicle arresting device" can be folded up for transport and storage, but unfolds to create a speedbump that remotely deploys a net to capture a vehicle tire and stop it from moving. The Pit-Bul allows normal traffic flow until the system is armed, and can be set up again for redeployment in less than 10 minutes. The company will also soon release the Viper, which is a remotely activated portable tire deflation device (a.k.a. spike strip).
