Here's my POV on burqas:
You put it on
Go to the store
Rob them
Get away
Nobody knows who you are
Now, I know that not everyone will do this. Probably nobody. But, it's extremely easy.
The least they could do is ban them while the person is driving. Those things must cut off a lot of the wearer's peripheral vision.
Also: Just because you're religion says you need to do it doesn't mean the country has to let you. That's not even the case in America.
If said "Religious requirement" is deemed as a safety hazard to others, the government has full right to end it in public areas. Private areas are iffy, so they normally allow it there if it's not too bad.
Also, if the requirement poses a danger to the general peace, it can be banned. Such with burqas.
In the past decade, the islamic reigion has gotten a bad reputation because of organizations of extremists such as Al-Queda. The burqa is also a well-known symbol of islam. So, if someone sees another person wearing a burqa, and their brother was killed in Iraq by muslim extremists, don't you think they would take their anger/sorrow/whatever out on the nearest muslim?
