Also, Java support isn't in windows by default now and you have to go to the Sun website to install it so that a lot of people will just get an X

I would recommend flash as it's all WYSIWYG so just get images of cars, one of the road and set animation paths and speeds for everything

Never done anything keyboard controled but I know it can be done ;)
You will have to buy Flash MX though if you don't already have it

yeah. i suppose java is abit out dated, but its for a reason that i wanna use java. i know flash, but i really need to use java. thanx for the advice
