To determine who drives on Tuesday, we need to consider the given information and apply logic to figure out the possibilities.

Let's break down the conditions:
- Sid will only sit beside his wife.
- Lucy won't sit in the front seat if her husband drives.
- Alice never sits in the front.

Based on these conditions, we can start narrowing down the possibilities:
- Alice never sits in the front, so she cannot be the driver.
- Lucy won't sit in the front seat if her husband drives. This implies that if Lucy's husband is driving, she cannot sit in the front. Therefore, if Lucy's husband is driving, Lucy must sit in the back.
- Sid will only sit beside his wife. So if Sid's wife is in the front, Sid must also be in the front.
- The car seats only 2 in the front and 2 in the back. Since Alice does not sit in the front, this means that if Alice is in the car, she must sit in the back.

Now, let's analyze the possibilities for each scenario:

If Sid's wife is driving:
- Sid will sit in the front seat beside his wife.
- Lucy won't sit in the front seat if her husband drives, so Lucy will sit in the back.
- Alice never sits in the front, so Alice must also sit in the back.
- Raymond will be left as the only person remaining, and he must be in the front.

If Lucy's husband is driving:
- Alice never sits in the front, so Alice will sit in the back.
- Lucy won't sit in the front seat if her husband drives, so Lucy must sit in the back.
- Sid will only sit beside his wife, who must be in the back seat.
- Raymond will be left as the only person remaining, and he must be in the front.

In both scenarios, Raymond is the only person who can drive. Therefore, Raymond drives on Tuesday.

In summary, Raymond is the driver on Tuesday.
