I drive SX4 and have gotten used to the view. Rear is still an issue but managing with mirrors.
BTW, each car has its own Pro's and Con's. It is only your priorities tell you what car you should go for.
If you are concerned lot about visibility, then mid-size and above will always be a problem for you, continue with small cars.
IMHO, this will just be initial hurdle until you are used to. So, don't worry about it. |
