Here's some code I quickly threw together. Let me know if the below output is closer to what you're looking for.

#!/usr/bin/perl

use warnings;
use strict;

use Data::Dumper;

my $data1 = [
{
   'NAME' => 'PAUL DY',
   'DATE' => '2009-05-05',
   'NUMBER' => '00001',
 },
 {
   'NAME' => 'ANTHONY RD',
   'DATE' => '2012-01-07',
   'NUMBER' => '00003',
 },
 ];

my $data2 = [
  {
    'CAR1' => '1',
    'CAR2'  => '2',
    'CAR3' => '3',
  },
  {
    'CAR1' => '1b',
    'CAR2'  => '2b',
    'CAR3' => '3b',
  },
];

my @results;

for my $data1_href (@$data1){
   
    my %current_row;

    for my $entry (qw(name date number)){
        $current_row{$entry} = $data1_href->{uc($entry)};
    }
    my $data2_href = shift(@$data2); 
    
    for my $entry (qw(car1 car2 car3)){
        $current_row{$entry} = $data2_href->{uc($entry)};
    }

    push @results, \%current_row;
}

print Dumper \@results;

Output (Dumper):

$VAR1 = [
          {
            'name' => 'PAUL DY',
            'car2' => '2',
            'car3' => '3',
            'number' => '00001',
            'car1' => '1',
            'date' => '2009-05-05'
          },
          {
            'date' => '2012-01-07',
            'car1' => '1b',
            'number' => '00003',
            'car3' => '3b',
            'car2' => '2b',
            'name' => 'ANTHONY RD'
          }
        ];

Here's an example on how to use each record:

for my $entry (@results){
    print "$entry->{name}\n";
    print "$entry->{car1]\n";
    #...etc.
