Movie with small robots that give lethal injections?
I'm trying to find the title to a movie I saw a long time ago, early 90's late 80's in which I remember only two things.
1. There are tiny robots that look like spiders with syringes on their front. They hide in small places and wait for someone to come near and when they are not looking they crawl out and stick them with their little needle. In one scene, a woman gets killed in a public bathroom stall by one of these robots.
2. During a high speed chase down a freeway the culprits are activating small remote control bombs which they lower onto the freeway through a hole in the vehicle and then drive them into position under other vehicles on the freeway before detonating them.
This movie was interesting in that it used such small toy like things to kill and destroy, any help would be appreciated thanks
