What feature is on cars that prevent breaks in while driving, or from road ragers?

I have the 2014 Ford Fiesta.
And I'm concerned that a road rager may try to attack me while in the car, as I've had close encounters.
There are a lot of angry drivers where I'm living. And I just want to know what feature, protect you from these people, by locking have all the doors locked from the outside.

Is this what power lock does?

Is this a good deal for a 2005 ford fiesta?

Ford Fiesta, 1.4L Zetec Climate 5dr

Got father to MoT and service the car and he says it is spotless underneath.

Paid £1350 for the car, is this a good deal and if i was to sell the car in say 1-2 years and i do roughly 10,000 miles, would i be likely to get my money back?

Why are some new cars still built with manual windows?

Manual windows seem outdated these days. Yet there are still manufactures that built cars without power windows.

The other persons insurances is paying for it and what not but the person that crashed in to me did not have a valid driver's license ( driving on a learners permit with out anyone in the car), ran a stop sign and did not clean all the ice off there windows to the point where the cops gave them a ticket for that to. I was wanting to know if there's anything I can sue?

Importing european car to USA an economically viable option?

I seen and heard that ford has a model fiesta ECOnetic thats only sold in europe and makes around 65 mpg (over 88.5 mpg now with the newer models).

I find it kind of weird that we can't get that same car in the states, so i want to ask the community if you guys think it would pay itself in the long run if i buy and import the car and modify it to meet US regulations (no point in doing all that work only to have a car i can't legally drive on the street).

What do you guys think? Is it worth the effort?

Will this cause damage to my Ford Fiesta ST?

Today I removed my scuttle plate on my car to remove a build up of leaves underneath. Before taking it off, the scuttle plate was touching the windscreen creating a kind of seal to stop water getting underneath it. This was quite tough to break the seal when removing the plate. Putting it back on however, the plate no longer touches the windscreen which allows water to now run underneath. The gap isn't very big but it looks like it needs some kind of seal to attach it back to the windscreen.

I just want to know if water runs underneath will this cause any damage? The windscreen edge is still sealed, but water can now run underneath the scuttle plate. Any ideas how to reveal it? I have a mk6 Ford Fiesta ST500, 2008 reg.
